From 6c95ab94f9f7e8d3156e4e16ecc7c499e141bb1a Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marc-Andr=C3=A9=20Lureau?= Date: Tue, 17 Apr 2012 14:32:35 +0200 Subject: [PATCH] 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?
