sound-problems with ALC262

Hi!

I posted a message at alsa-user list just yesterday about my problem
with the on-board ALC262 on my workstation, see mailings lists archive:
http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg23236.html

Quote from my initial post:
| I just got a new workstation. It's an Fujitsu-Siemens Esprimo P5625
| with an on-board ALC262 sound chip. I'm running a Kubuntu 8.04.1 on
| that system.
|
| The sound I get from that chip is really horrible. There are
| cracks and some kind of a reverberation in there.
|
| I compiled the recent version of alsa (1.0.17) and I tried all the
| model-options for /etc/modprobe.d/alsa-base.

"stan" told me to use this script
http://www.alsa-project.org/alsa-info.sh  to create more information
about my system. Here is the pastebin link of the output of that script:
http://pastebin.ca/1169153

Maybe I can help evolve the snd-hda-intel by being a tester.
Unfortunately my kernel-hacking skills are as rusty as my C skills -
because of being a Java developer for some years now.

Tobias

At a quick glance, I see no problem in the configuration.

Does the problem exist even if you play via PCM "hw" device, such as

	% aplay -Dhw foo.wav

??
If your WAV file isn't with the supported format/rate, use plughw: 

	% aplay -Dplughw foo.wav

What happens when you load the driver with bdl_pos_adj=0 option?

The reverberation increases a little.
