David, I have tested the dkms in one more machine based on the same motherboard using first a fresh install of Natty, and then updated it to Oneiric. In both cases, there really is no change to /proc/asound/SB/codec#0 when headphone is plugged / unplugged to front jack. Just to make sure it is working, I installed Windows 7 later and verified that in fact Jack sense works on that OS.
I verified a new information (don't know if it makes any difference in this case). In the BIOS of this motherboard, the user can choose between HD and AC'97 for the front panel connectors. I verified that I have sound in headphone and mic working in both cases and that sense does not work for headphone in any. What method (HD or AC'97) is preferable for Alsa /hda? Or is your code independent of that choice? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/871582 Title: M4A89GTD_PRO_USB3/Realtek ALC892, Green Headphone Out, Front] Playback problem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/871582/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
