GNOME Bugzilla – Bug 600363
Digital/Analog Audio Profile
Last modified: 2010-03-08 14:58:25 UTC
I'm using Ubuntu Karmic Koala and the Gnome Sound Preferences dialog now has a Profile option for selecting Digital vs. Analog audio. It does not give the option to use both, which I need. I have Digital Output and Analog Input selected, and my headphones do not work. If I select Analog Output, they work. I simply need to be able to use both. $ uname -a Linux anubis 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009 x86_64 GNU/Linux $ apt-cache policy gnome gnome: Installed: (none) Candidate: 1:2.22.2~4ubuntu8 Version table: 1:2.22.2~4ubuntu8 0 500 http://us.archive.ubuntu.com karmic/universe Packages
Also, I forgot to mention... When selecting Digital Output, you have to use the alsamixer to unmute IEC958/PCM in order to get it to work.
That's not a problem for gnome-volume-control, it's a PulseAudio problem. gnome-volume-control only presents the profiles that PulseAudio makes available. File a bug against your distribution or against PulseAudio itself.
