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. Signed-off-by: Marc-Andr? Lureau <marcandre.lureau@redhat.com> Signed-off-by: malc <av1474@comtv.ru>
