Patch 22 was specific to a few HP laptops with the CX20551 codec (you have the CX20549). The driver has been undergoing quite a bit of refinement over the last few months, so I'm not sure which version is in what kernels. The best thing to do is download the alsa-driver-1.0.14rc4.tar.bz2 release from alsa-project.org and use it. It is the most current for that codec.

Hi!
First of all: Sorry if this question is dumb or a fix should be obvious, but as a non-ALSA_expert I'm a bit a a loss at the moment... I searched the bugtracker and this list but could not find anything appropriate - most probably I missed a relevant post or didn't recognize it as being relevant...
Any pointers are greatly appreciated!
The situation is as follows: Using Linux 2.6.20.4, my laptop's soundcard works just fine. Using 2.6.21.1, it also works, but the headphone socket is dead. Plugging a headphone into it correctly mustes the internal speakers, but no sound is output via the headphones.
Details:
- Fujitsu Simens Amilo Si1520
- Codec: Conexant ID 5045 (as reported by Linux 2.6.20.4)
Alsa device details between both Linux kernels differ completely, with Linux 2.6.20.4 only reporting a single a single analog PCM device and Linux 2.6.21.1 reporting a Conexant Analog and a Conexant Digital device. Should I still post the complete information from /proc/asound/* for both kernels?
I tried applying conexant-test22.patch by Tobin Davis, but it does not seem to match the in-kernel ALSA code. It also does not seem to be related to the 5045 chip...
Any ideas?
