Release a sound device that was allocated with register_sound_dsp () . The unit passed is the return value from the register function. Both of the allocated units are released together automatically. int snd_pcm_stream_linked( struct snd_pcm_substream * substream) ¶. Check whether the substream is linked with others.

The Linux kernel audio driver documentation is available in the kernel sources, please refer to How to build kernel for Android for more information. By default, audio is enabled within the kernel, adding the following lines within the android-soc.config available in kernel sources. CONFIG_SND=y CONFIG_SND_TIMER=y CONFIG_SND_PCM=y ... Two options:

ALSA (Advanced Linux Sound Architecture) is the current sound system for the Linux kernel. An earlier sound system (OSS) has been deprecated, and almost all of the older drivers have been removed from the kernel source tree. To determine which type of sound controller is present in your machine, and what type it is, run the following command:

The children of the /soc node are memory mapped devices, but the codec @ 1a is an i2c device, and the sound node represents not a device, but rather how other devices are connected together to create the audio subsystem. I know what each device is because I’m familiar with the board design, but how does the kernel know what to do with each ...
