Hi Daniel,
Sorry for the delay with my feedback. I've done the following and
verified that jack sense is working. I'll attach my
/proc/asound/card*/codec* info. I'll also attach my
/proc/asound/card*/codec* info when passing in probe_only=1.
1) Made sure any model quirks have been removed from alsa-base.conf:
ogasaw...@emiko:~$ grep -n "snd-hda-intel" /etc/modprobe.d/alsa-base.conf
42:options snd-hda-intel power_save=10 power_save_controller=N
2) Installed linux-backports-modules-alsa-karmic-generic (note I'm
running a bleeding edge pre karmic-proposed kernel hence the ~pre1 in
the version)
ogasaw...@emiko:~$ apt-cache policy linux-backports-modules-alsa-karmic-generic
linux-backports-modules-alsa-karmic-generic:
Installed: 2.6.31.16.29~pre1
Candidate: 2.6.31.16.29~pre1
Version table:
*** 2.6.31.16.29~pre1 0
500 http://ppa.launchpad.net karmic/main Packages
100 /var/lib/dpkg/status
2.6.31.14.27 0
500 http://us.archive.ubuntu.com karmic/universe Packages
3) Rebooted (again note I'm running a bleeding edge pre karmic-proposed
kernel)
ogasaw...@emiko:~$ uname -a
Linux emiko 2.6.31-16-generic #50~pre1-Ubuntu SMP Thu Nov 5 17:34:39 UTC 2009
i686 GNU/Linux
ogasaw...@emiko:~$ cat /proc/version_signature
Ubuntu 2.6.31-16.50~pre1-generic
4) Verify sound is working and jack sense is properly working.
