Hi,
I hope this is the right place to report this.
Computer: laptop Acer Aspire 1640Z
distro: Debian etch kernel: 2.6.17
[...]
hda_codec: Unknown model for ALC882, trying auto-probe fromBIOS...
but alsamixer shows: Card: HDA Intel Chip: Realtek ALC883 at the top.
There seems to be uncertainty about which model number, 882 or 883.
Your kernel is 2.6.17. Its alsa driver is too older. It didn't provide patch_alc883 for ALC883 codec, but used the patch_alc882 for it. AND there is no "model acer" in it.
I have tried with the latest kernel in debian etch (2.6.18) This gives same error but with correct model number, ie hda_codec: Unknown model for ALC883, trying auto-probe from BIOS... when trying to load either model=acer or acer-aspire
It looks as though I have to wait to try kernel 2.6.24 as in debian unstable. When I have a fast internet connection one day, I shall try this. It is not practical or affordable to upgrade over GPRS.
You can build alsa-driver modules externally. It's more standard procedure for debugging sound problems. Just configure and install as usual. See alsa-driver/INSTALL for details.
In your case, maybe better to try alsa-driver daily snapshot tarball than 1.0.16. See alsa-driver.project web page.
