No Sound on Laptop

[f4nt]

After feeling a bit hosed by Jaunty, I'm back to Sabayon which I've used a little bit in the past. This time around though I'm on a new laptop, an Acer Aspire 6920, which apparently has a PITA for a sound card. My Alsa info can be found at:

http://www.alsa-project.org/db/?f=63acc ... c37410b786

Now I had numerous problems in Ubuntu as well with Heron, Intrepid, and Jaunty, however I was always able to update Alsa to 1.0.19 and it worked fine. However it would seem that 1.0.20 is the default in Sabayon 4.1 if I'm not mistaken. Yet I don't get any sound out of the speakers, or headphone jack. Anyone have some ideas on things I could try to solve this issue in Sabayon? I'd really like to stick with this distro for awhile, but sound's a bit of a necessity. Thanks in advanced for any/all help.

The first thing to do in such cases is to open up a console,
type su and your root password and execute:

Code: Select all

alsaconf


hopefully it will configure the card for you.

[f4nt]

Tried that, selected my card and such.. no dice :/

[micia]

you are also sure that all channels are setup properly?
Check it with:

Code: Select all

alsamixer


Sometimes channels get a low volume and it seems that the
card is not recognized.
If still no luck, could you post the output from lspci and tell us the model of your laptop?

[f4nt]

All the channels show up properly and I have them all cranked. None of them are muted either.

Code: Select all

Thanks for the tip. Unfortunately the following line:

Code: Select all

modprobe snd-hda-intel "YOUR_MODEL"

keeps failing on me. I've tried multiple modules but always receive:

Code: Select all

FATAL: Error inserting snd_hda_intel (/lib/modules/2.6.29-sabayon/kernel/sound/pci/hda/snd-hda-intel.ko): Unknown symbol in module, or unknown parameter (see dmesg)


Below is an example of the line I've ran:

Code: Select all

modprobe snd-hda-intel ALC268


Dmesg doesn't say much other than the parameter (the model number) is unknown. Am I missing something obvious here?

[f4nt]

Nevermind, looks like it's supposed to say "model=MODEL_NAME". Found that in the forums. I'll give it a shot and see what happens I *hate* this sound card.

[f4nt]

Tried a myriad of different models, still no sound. I'm either doing something wrong, or my card is just really annoying. Not sure which yet.

f4nt I had the same problem with my Acer Aspire 8920g. This is what I did to fix it.

Step 1: Open Terminal from "Applications->Accessories->
Terminal"

Step 2: Run the following commands (copy/paste each command into the
Terminal and then hit <enter>)

gedit /etc/modprobe.d/alsa-base

Add these 2 lines to the end of the alsa-base file:

alias snd-card-0 snd-hda-intel
options snd-hda-intel model=auto

It worked for me after weeks of searching. Many thanks and credit go to Mark Rijckenberg for his help in this matter.
Hope it works for you too.
