I had this same problem as this on my new Karmic setup with the same VIA VT1708B on a Asus M2N68 mainboard with AMD 64-bit cpu. This was a new Karmic install not an upgrade.
My first big (very big) mistake was trying to use a front panel AC'97 connector that came with my mini-tower. Changing to a HD Audio connector fixed that so that I could see that the headphone was dectected using a: > sudo ./hda-verb /dev/snd/hwC0D0 0x1d 0xf09 0 command showed: > value = 0x80000000 Next I played with alsamixer and when the Independ column is set to OFF then the front headphone jack starts to work. The column is off to the right on the alsamixer display. But using GNOME ALSA Mixer and changing the Independent HP check box has no affect. -- Codec: VIA VIA VT1708B 8-Ch - VT1708B Analog audio device - Audio device: nVidia Corporation MCP67 High Definition Audio (rev a1) - working via speakers but not via headphone jack on Asus M2N-CM DVI motherboard in Ubuntu 9.04 https://bugs.launchpad.net/bugs/381297 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
