Here I send the two also-info files as attachments.

Initial problem was: Under kernel 2.6.30, Sound is working, but has constant clicking noise in the background, also if the sound is completely muted. First I thought this sound would come from some hdd or whatever, but the device has no mechanical parts. But this is what it sounds like - Irregular clicking noise.

This noise immediately starts during boot up as soon as the module is loaded and before X11 has started. I already tried options like "position_fix=1 or 2" and different "model="-options with no success. "position_fix" didn't do anything at all and different model-options have muted the device completely.

Kernel 2.6.24 with the same files has no issues.

...

Then give as attachments later (and don't forget Cc to alsa-devel ML) these two files, not URL. It's important because ML is archived while pastebin can be removed at any time.

Thanks, Christian Steffen

Well, then at least, the contents of /proc/asound/card0/codec#*, /sys/class/sound/hwC0D*/*_pin_configs files (if present), and the file generated via "alsactl -f somefile store". These are the most important information.

There is no pinconfig file and there is also no alsactl tool present. I could obtain the output from the codec stuff:

http://pastebin.com/m1b81f47d (old kernel 2.6.24, only the codec info) http://pastebin.com/m5baeca9a (new 2.6.30)

that's all I could get for the older kernel as I only have access using telnet.
