[Hardy] Sound doesn't work out of the box on Acer TravelMate 6292 (Alsa HDA INTEL driver / Realtek ALC268 Codec)

[Fred]

Sound doesn't work out of the box on an Acer TravelMate 6292 laptop.
This laptop has an Intel HDA with chipset "Realtek ALC268".
In order to make sound works, you need to tweak /etc/modprobe.d/alsa-base to replace the following line :
options snd-hda-intel
with:
options snd-hda-intel model=acer

It would be really really nice for Hardy Heron to have sound working out the box.

Laptop info (as reported by dmidecode) :
system-manufacturer:Acer, inc.
system-product-name:TravelMate 6292
system-version:Not Applicable

If you are needing more informtion, just let me know please.

I am having a similar issue on my lenovo t61, although I have not attempted the 'model=BRAND' setting. I will comment here when I do.

Please see the DebuggingSoundProblems wiki page and attach the output from the script or "lspci -nv|grep -A1 0403".

Daniel,
Here is the output of "lspci -nv|grep -A1 0403" :
$ lspci -nv|grep -A1 0403
00:1b.0 0403: 8086:284b (rev 03)
        Subsystem: 1025:011b

Just to be clear, this bug is not about making sound works. Sound works after you tweak /etc/modprobe.d/alsa-base file. More on bug #116326.

This bug report is about making sound "Just works".
For example, is it possible to implement the following behavior ?
At the end of installation, identify the laptop model (with dmidecode), the alsa driver and the codec and modify accordingly /etc/modprobe.d/alsa-base so that sound works out-the-box.

I did not need to set the brand, it seems that alsa muted my speaker ... in the past it has muted PCM. All is good for me.

[Leon (leonbo)]

I had the same problem. After upgrading, a week ago or something, alsa muted my front speakers. After unmuting it worked again.

[Fred (frederic-lespez)]

In Hardy Alpha 5, sound works out of the box !
No need to tweak alsa configuration files.

[Fred (frederic-lespez)]

This issue seems to have been fixed in Alsa 1.0.16 + post_16_20080214.patch.

I installed Ubuntu 8.04 (x86) on an Acer TravelMate 5520 (ATI Technologies Inc SBx00 Azalia / ALC268) last week and I can confirm that sound works out-of-the-box (everything but microphone, which I have not been able to get working).

Strange that it worked somewhat ok in Ubuntu 8.04 but it does not in Ubuntu 8.10.
