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.

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.
