3Subject: alsa: allow configuration of fallback device strings in profiles
4X-Git-Url: http://git.0pointer.de/?p=pulseaudio.git;a=commitdiff_plain;h=d8710711fb0c74b4ad83ac99c2501218155b502b

6alsa: allow configuration of fallback device strings in profiles
7
8This has the benefit that we can properly support ALSA devices where
9only the raw 'hw' device exists but no 'front' although it's a proper
102ch stereo device.
