ubuntu 12.04 sound problem

[adityeah]

Hi,

I am using an intel DG31PR motherboard that has realtek audio. Ever since I have installed Ubuntu 12, the audio is not working right. I hear the sound (from the speaker) but its mostly absent. Basically there is a lot of stuttering/choppiness. If I use a headphone, it works fine.

I have my alsa diagnostic tool output up at: http://www.alsa-project.org/db/?f=ba...8a9446c277a2a3

I have tried all I could but nothings working for me. I must mention that before this I was using xubuntu 11 which worked just fine (I never updated it because I found that one of the updates to xubuntu 11 caused the same problem that I am facing now).

Any help would be appreciated. I would be forced to look back at other options if this does not get solved soon.

Thanks!

Aditya

Since no one replied I started snooping around myself. Till now what I have found is that the alsa output thinks that I have a Realtek ALC662 but in reality what Intel DG31PR comes with is ALC888. So that might be a problem, I am guessing.

Right now I do not have access to my system but soon I will and will try and see a fix for that. Will update it here.

Hey mate!

Since your headphones are working fine I would guess it is rather a problem with the way the sound is going to your speakers, obviously.. I am probably stating the obvious, but have you played around with different mixers (e.g. gnome alsa mixer, alsamixer in terminal [command: # alsamixer] etc) to see if that sorts things out?

ah, we have a reply at last.

Yes, I did some tweakings with alsamixer (only alsamixer, nothing else) and did not help.

The sound from the speaker is MOSTLY absent and when I hear some, for those microseconds that its there, its choppy.

Any help or thoughts appreciated!

Moved to the multimedia forum.

Have you looked in the software centre for a different sound system to try? or uninstall what you currently have and reinstall it??

Solved!

Here's what I did:

added this line at the end of /etc/modprobe.d/alsa-base.conf:

options snd-hda-intel model=generic

That was all. I think I had tried it earlier too but somehow it was not working. Maybe I had tried too much.

But I think the problem was indeed that it was trying to use the ALC888 as ALC662 and that was not happening.

Thanks for the responses. Now I can stick to Ubuntu and try to get friendly with Unity
