I think this may be related to a much older bug report # 218906 which was opened back in April of 2008 but never resolved. A work around that was suggested then, and which I have used successfully through Jaunty, Karmic and Lucid is to add the following line to the bottom of /etc/modprobe.d/alsa-base.conf :
options snd-hda-intel model=3stack-6ch-dig A check with GNOME Alsa mixer shows both the CD and Aux inputs are now available. The problem is likely caused by, to quote JoePub from Aug of 2008, "It seems the auto configuring of the available HDA widgets from the BIOS is not working on the GA-MA78GM-S2H." -- CD/AUX input not detected https://bugs.launchpad.net/bugs/620891 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
