Subject: [PATCH 501/509] audio: add VOICE_VOLUME ctl
|
|
|
|
Add a new PCM control operation to update the stream volume on the
|
|
audio backend. The argument given is a SWVoiceOut/SWVoiceIn.
|
|
|
|
v4:
|
|
- verified other backends didn't fail/assert on this new control
|
|
they randomly return 0 or -1, but we ignore return value.
