I don't have any problems with this bug anymore on Natty. So I can confirm that this is fixed for me with alsa-lib - 1.0.24.1-0ubuntu4.
@ David Henningsson Thank you for your tip with the ttable entries. I was not possible to make a mapping through via-ice1712.conf (but perhaps I just did something wrong), but changing /usr/share/alsa/cards/ICE1712.conf works to allow simultanuous output on channels 1-4. Here the relevant section in /usr/share/alsa/cards/ICE1712.conf, where I added the two lines you suggested: <confdir:pcm/front.conf> ICE1712.pcm.front.0 { @args [ CARD ] @args.CARD { type string } type asym playback.pcm { type route ttable.0.0 1 ttable.1.1 1 ttable.0.2 1 ttable.1.3 1 Thanks a lot -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/178442 Title: Pulseaudio fails to initialize ICE1712 chipsets -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
