Hi, It says "If the default configuration doesn't work and one of the above matches with your device, report it together with the PCI subsystem ID (output of "lspci -nv") to ALSA BTS or alsa-devel ML" in ALSA-configuration.txt so, here it is:
i'm using asus p5ld2-se mobo with intel ich7 chipset, and just have installed new debian stable (4.0). And encountered a problem: onboard audio sound from one of the speakers was just static noise, and if i adjusted volume or anything in alsamixer, the sound kept dissappearing. I tried module=3stack option in modprobe, added line options snd-hda-intel index=0 model=3stack in /etc/modprobe.d/sound and everything is ok now.
i attached lspci -nv output to this letter
p.s. on ubuntu live cd and other distros i've tried there were same problem
