Mikhail Naganov	f12d4a1ef8	audio: Simplify and extend alsa::Mixer ... Remove alsa::MixerControl. tinyALSA contains utility functions for setting values in percents, they use the same logic as used to be there for handling the "volume" control. Use access serialization at the mixer level, rather than for each control. Move the call to 'mixer_open' to alsa::Mixer. Add controls for capture (mic) mute and gain. They will be used by the primary HAL. Bug: 264712385 Test: atest VtsHalAudioCoreTargetTest Change-Id: I0fad994153de96aceec3eb8f2fec19805ec912f8	2023-07-19 17:35:38 -07:00
Mikhail Naganov	c337a8799b	audio: Move tinyALSA-specific code to Module/StreamAlsa ... Extract code interacting with tinyALSA which is not specific to USB into "abstract" module and stream implementations ModuleAlsa and StreamAlsa. Also, move utility code which does not need module or stream context into Utils. This facilitates implementation of the CF core HAL which also uses tinyALSA, allowing to share common code.
