snd-hda-intel problem

[Anonymous]

hello all!

First, I couldn't make Audio work.

I ran "lspci | grep -i audio" to find out which was my audio card 

The output was:

0000:00:1b.0 0403: Intel Corp. 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03)

Reading every article I could have found on the net regarding this card, I discovered that i needed snd-azx (ALSA 1.0.8 ) or snd-hda-intel modules (ALSA 1.0.9rc* or later).

I could make audio work but it was scratchy, noisy or disorted. Like when volumen is high; however, audio in XP is louder and sound 100% ok.

Following the steps from here: http://www.ubuntulinux.org/wiki/HdaIntelSoundHowto

I downloaded the lastest files from http://www.alsa-project.org to build and install ALSA 1.0.9 (1.0.9 release not the release candidates) and lately 1.0.9b.

I've looked every on the net and found that I could use position_fix=1 or position_fix=2 to help me out but no good.

I've tried in Ubuntu, Kubuntu, Debian and Fedora Core 4 (using the modules from the kernel) and it's the same problem in all of them.

The card came with the mainboard Intel 915G (D915GEV or 915GEV)

Thanks for the help,
Santiago

Have the same problem here but I have a
ASUS P4GPL-X and a Realtek ALC880.
Never saw this have 5 Mobos from 915P - 955X never had this issue and there all works.

lspci -vv gives me
