Bug Description

experienced problem:
When I plug a headphones into the front panel audio connector, sound comes from both back panel connected speakers and front panel connected headphones. The sound profile remains at 5.1 channels.

expected behavior:
The back panel audio should be muted/disabled when plugging and unmuted/enabled when unplugging the front panel connector. Also, it would be nice, if the audio profile switches to stereo when something is plugged to the front panel line-out, and back to the previous profile when unplugged. (I didn't find anything about it being implemented to the linux sound stack though.)

what I did try and find out so far:
- installed https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules (with kernel 2.6.35-24-generic)
- "aplay -l" does not list a seperate front panel audio device (output included).
- I wanted to retrieve a codec dump (as in https://wiki.ubuntu.com/ALSA/JackSense) but there are no files matching /proc/asound/card*/codec*.

Any ideas where to find more useful debug output? I'm willing to dig a little deeper but I didn't find hints on where to look for plugging/unplugging events. At least dmesg remains unchanged.

I almost forgot: symptoms are identical with 2.6.35-24-generic and the reporting kernel 2.6.37 from Linus' git. I can provide the -35 reports as well if necessary and see what diff tells me about them.

This is still an unresolved issue on a fresh install of Ubuntu 20.04 (preview). Jack sense on my SB0880 is nonexistent whatsoever in ALSA.
