Title:
jack sense does not work with emu20k2 chips (Creative X-Fi Titanium
cards)
Status in alsa-driver package in Ubuntu:
Incomplete
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.
