DETAILED DESCRIPTION

[0044] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be clearly and completely described below in conjunction with the drawings in the embodiment of the present application. Obviously, the described embodiment is only a part of the embodiment of the present application, rather than all the embodiments.

In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily. In addition, although the logical order is shown in the flow chart, in some cases, the steps shown or described can be performed in an order different from that here.

[0045] In a dual system where Android is embedded in Linux, the steps of the prior art are as follows:

[0046] Step 1: Enter the shell environment in the Android system.

[0047] Step 2: Start the pulseaudio service and set the PULSE_SERVER environment variable.

[0048] Step 3: Enter the embedded Linux environment and start the pulseaudio client.

[0049] Step 4: The pulseaudio client successfully connects to the pulseaudio service.

[0050] Step 5: Successfully play sound with pulseaudio.

[0051] In the prior art, audio data in the Linux system needs to be processed and transmitted by the Android system, which may introduce additional delays and cause a longer delay in audio output. In addition, the transmission of audio data through the proxy service may cause data loss or compression, thereby causing a decrease in audio quality.

[0052] In view of this, the present application embodiment provides a method for playing Linux audio in an Android device, which can be applied to an Android device, please refer to Figure 1 , which is a schematic diagram of the Android device structure of the hardware operating environment involved in the embodiment of the present application.

[0053] like Figure 1 As shown, the Android device may include: a processor 101, such as a central processing unit (CPU), a communication bus 102, a user interface 104, a network interface 103, and a memory 105. Among them, the communication bus 102 is used to realize the connection and communication between these components. The user interface 104 may include a display screen (Display), an input unit such as a keyboard (Keyboard), and the user interface 104 may include a standard wired interface and a wireless interface. The network interface 103 may include a standard wired interface and a wireless interface (such as a wireless fidelity (WIreless-FIdelity, WI-FI) interface). The memory 105 may be a high-speed random access memory (Random Access Memory, RAM) memory, or a stable non-volatile memory (Non-Volatile Memory, NVM), such as a disk memory. The memory 105 may optionally also be a storage device independent of the aforementioned processor 101.

[0054] Those skilled in the art will understand that Figure 1 The structure shown in the figure does not constitute a limitation of the device, and may include more or less components than shown in the figure, or combine certain components, or arrange the components differently.

[0055] like Figure 1 As shown, the memory 105 as a storage medium may include an operating system, a network communication module, a user interface module, and a device for playing Linux audio in an Android device.

[0056] exist Figure 1In the Android device shown, the network interface 103 is mainly used for data communication with the network server; the user interface 104 is mainly used for data interaction with the user; the processor 101 and the memory 105 in the Android device of the present invention can be set in the Android device, and the Android device calls the device for playing Linux audio in the Android device stored in the memory 105 through the processor 101, and executes the method for playing Linux audio in the Android device provided in the embodiment of the present application.

[0057] based on Figure 1 For the Android device shown below, Figure 2 The following is a method for playing Linux audio on an Android device.

[0058] S201. In the Android system of the Android device, open the target sound card and the target audio device.

[0059] Among them, Android devices generally refer to various hardware devices running the Android system, such as smart phones, tablet computers, IoT devices, etc. Usually, Android devices are only provided with a single Android system.

[0060] In a possible embodiment, before executing S201, the method may further include the following steps:

[0061] Use the preset mode to embed the Linux system into the Android device; the preset mode is Proot mode, Chroot mode, or Docker mode.

[0062] In the specific implementation process, Proot mode is suitable for users without root privileges and can quickly build a lightweight Linux environment. Chroot mode is suitable for users who need higher performance and better isolation, but they must have root privileges. Docker mode is suitable for users who need high isolation and containerized environment, but requires additional system support. Therefore, according to the permissions of the Android device and the actual needs of the user, any mode among Proot mode, Chroot mode and Docker mode can be selected as the preset mode, and a Linux system can be embedded in the Android device using the preset mode.

[0063] In the embodiment of the present application, a Linux system is embedded in an Android device, so that the Android device changes from a single Android system to a dual system supporting Android and Linux, which can significantly improve the functionality, flexibility and performance of the Android device and meet higher-level usage requirements.

[0064] In a possible embodiment, before executing S201, the method may further include the following steps:

[0065] From all the sound cards of the Android device, determine the sound card corresponding to the hole where the headset is inserted as the target sound card; determine the audio device under the target sound card as the target audio device.

[0066] In the specific implementation process, the information of all sound cards on the Android device can be obtained. If the Android device is plugged into a headset, the sound card corresponding to the hole where the headset is plugged in is preferentially determined as the target sound card. If the Android device is not plugged into a headset, the default sound card (such as a speaker) can be determined as the target sound card. Then, the audio device under the target sound card is determined as the target audio device, and the target audio device includes a target playback device and a target recording device.

[0067] In an embodiment of the present application, when a headset is inserted into an Android device, the system will automatically select the correct target sound card and the audio device under it as the output device. This can prevent the audio from continuing to be output to the built-in speakers or other unnecessary devices of the Android device, ensuring that the audio stream is accurately output to the headset rather than the default speakers or other external devices.

[0068] In a possible embodiment, S201 may include the following steps:

[0069] In the Android system of the Android device, use the tinymix command to open the target sound card and target audio device.

[0070] Specifically, the tinymix command of the Android system serves as a user interaction tool that allows users to interact with the configuration and settings of audio hardware. Through the tinymix command, users can easily interact with the audio hardware in Android devices and open, enable or disable various audio devices and output paths.

[0071] S202. In the Linux system, modify the access rights of the target sound card and the target audio device to the pulseaudio service.

[0072] In a possible embodiment, in the / dev / snd folder of the Linux system, the permissions of the target sound card and the target audio device are modified to the pulseaudio service.

[0073] Specifically, in Linux systems, the / dev / snd folder contains device nodes related to the sound card, which are used to access audio input and output. The device files in the / dev / snd directory usually require specific permissions to ensure that the audio hardware can be used normally. In order to allow the pulseaudio service to have permission to access the target sound card and target audio device after it is started, it is necessary to modify the permissions of the target sound card and target audio device so that they can be read and controlled by the pulseaudio service.

[0074] S203: Configure the target sound card and the target audio device in the configuration file of the pulseaudio service.

[0075] Specifically, pulseaudio is a common audio server on Linux systems, which provides rich functions to manage audio devices and audio streams. By modifying the configuration file of the pulseaudio service and configuring the target sound card and target audio device, the pulseaudio service can monitor the opened target sound card and target audio device after it is started.

[0076] S204, start the pulseaudio service, control the target sound card and the target playback device, and play the audio of the Linux system.

[0077] In a possible embodiment, the pulseaudio service is started, and the target sound card and the target playback device are controlled by the paplay tool to play the audio of the Linux system.

[0078] Specifically, the pulseaudio service is usually started automatically when the Linux system starts. If not, you can manually enter the command line "pulseaudio --start" to start the pulseaudio service. paplay is a command line tool for playing audio files through pulseaudio, allowing users to play audio files through pulseaudio and specify the target playback device to play the audio of the Linux system.

[0079] In a possible embodiment, after executing S204, the method may further include the following steps:

[0080] Use the parecord tool to control the target sound card and target recording device to record the audio of the Linux system.

[0081] Specifically, parecord is a recording tool provided by the pulseaudio service. It can be used to specify the target recording device to record the audio of the Linux system. Other options can also be used to adjust the quality of the recording, such as setting the sampling rate, setting the volume, setting the recording duration, setting the recording format, etc. parecord saves the recording in .wav format by default, but you can also choose other formats, such as .ogg or .flac (requires system support). Specific embodiment 1:

[0083] like Figure 3 As shown in FIG. 1 , a schematic diagram of a specific process of playing Linux audio on an Android device provided in an embodiment of the present application is shown. The process can be performed by Figure 1 The process is performed by the Android device shown in the figure. The Android system and the Linux system have been set up in the Android device. Specifically, the process is described as follows.

[0084] S301. In the Android system, use the tinymix command to open the target sound card and target audio device.

[0085] S302. In the Linux system, in the / dev / snd folder, modify the permissions of the target sound card and the target audio device.

[0086] S303. In the Linux system, configure the target sound card and the target audio device in the configuration file of the pulseaudio service.

[0087] S304. In the Linux system, start the pulseaudio service.

[0088] S305. In Linux system, use paplay to play audio.

[0089] S306. In Linux system, use parecord to record audio.

[0090] It should be noted that the execution order of S305 and S306 is not specific, they can be swapped, and can also be executed simultaneously. Specific embodiment 2:

[0092] Assuming that the Android device is Rockchip's Rk3588 device, which has been configured with the Android system and the Linux system, the following process can be used to explain the technical solution of the present application in detail.

[0093] First, you can enter the command line "cat / proc / asound / cards" to view all sound cards on the Rk3588 device, and you can enter the command line "cat / proc / asound / devices" to view the audio devices under each sound card.

[0094] like Figure 4 As shown, it is a schematic diagram of a code for viewing all sound cards and audio devices provided by an embodiment of the present application. Figure 4 It can be seen that all sound cards on the device Rk3588 include sound card 0, sound card 1 and sound card 2, among which sound card 2 is the sound card corresponding to the hole where the headset is inserted, so sound card 2 is used as the target sound card, and audio device 0 under sound card 2 is used as the target audio device.

[0095] Secondly, in the Android system, you can enter the command line "tinymix 38 1 -D 2" to open sound card 2, such as Figure 5 As shown, it is a code schematic diagram for opening the sound card provided in an embodiment of the present application.

[0096] Next, switch from Android system to Linux system, modify the audio device 0 under sound card 2 in the / dev / snd folder, so that the pulseaudio service has the permission to read and control the audio device 0 under sound card 2 after startup, such as Figure 6 As shown, it is a code schematic diagram of the modification permissions provided in an embodiment of the present application. It can be seen that the audio devices under the sound card 2 include controlC0, pcmC2D0c and pcmC2D0p.

[0097] Then, in the Linux system, continue to modify the pulseaudio configuration file, configure sound card 2 and audio device 0 under sound card 2, such as Figure 7 As shown, it is a code schematic diagram for configuring a sound card and a device provided in an embodiment of the present application.

[0098] Furthermore, start the pulseaudio service in the Linux system, and the pulseaudio service can access sound card 2 and audio device 0 of sound card 2.

[0099] Finally, you can enter the command line "paplay -vv test_paplay.wav" to use pulseaudio's built-in tool paplay to play the audio file with the path "test_paplay.wav", such as Figure 8As shown in FIG. 1 , a code schematic diagram of playing audio provided by an embodiment of the present application is shown, wherein paplay is a play command, -vv indicates printing information, and test_paplay.wav is an audio file to be played. You can also enter the command line "parecord -vv test_parecord.wav" to indicate that the audio file with the path "test_parecord.wav" is recorded using the built-in tool parecord of pulseaudio, such as Fig. 9 As shown, it is a code schematic diagram for recording audio provided in an embodiment of the present application, wherein parecord is a recording command, -vv represents print information, and test_parecord.wav is a new recorded file.

[0100] To summarize, the embodiments of the present application provide a method for playing Linux audio in an Android device. In an Android device with an Android+Linux dual system, by modifying permissions and configuring the sound card and device, the pulseaudio service is used in the Linux system to directly drive the sound card and device, thereby realizing the playback and recording of Linux audio. Since it does not need to be processed and transmitted by the Android system, the Linux system provides more direct hardware control, which can reduce the delay of audio playback and improve the audio quality.
