Greetings. I thought I should mention that your patch
http://kerneltrap.org/mailarchive/git-commits-head/2008/2/1/670694
broke headphone sound for me on a Toshiba Satellite P105-S6197,
sound card PCI ID 8086:27d8 with Conexant CX20549 codec. The speakers
silence when I plug the headphones in but no sound comes from them.
Do you mean that the no sound comes from the headphone even if you
plug it?  And, the speaker works again after unplugging the HP?
Yes.
...
...
...
Details are at http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=488063
but half of my Debian bug reports go ignored for years.
A sufficient workaround for me is to comment out the `default:' in the
`switch (board_config)' in the function `patch_cxt5045' in
sound/pci/hda/patch_conexant.c. Then everything works fine again.
Does the speaker auto-muting work if you do that?
Yes.
In both cases, the speakers work fine: they mute if I plug the
headphones in, and unmute when I unplug them.
The difference is that if I leave the `default:' in the code, no sound
comes from the headphones when they are plugged in.
...
Please run alsa-info.sh (with --no-upload option) for both working
(patched) and non-working (the original) cases, and attach generated 
files to compare.  This will be helpful to analyze the problem.
Okay.
