Wierd sound problem on ASUS F5SL based laptop
 

I have the following problem with sound on my ASUS F5SL based laptop.

The first time when I installed slackware, the sound worked with following hack:
options snd-hda-intel position_fix=1
added to /etc/modprobe.d/sound.

In the meantime i had to reinstall Slackware and now i have a problem. The sound no longer works with given hack?!! :confused:

I wonder if someone has an idea where to start with the analysis of this problem, or maybe an solution?

I forgot to mention it is Slackware 12.1. And only thing that might be different from previous installation is running alsaconf before alsamixer (I can`t remember whether I did the same the first time).

One more thing, first time i did config with huge-smp kernel. Next time i did it with generic-smp kernel.

I believe that just because you've set options for snd-hda-intel doesn't mean that it's loaded as a module. I would check and make sure that it is. I bet if you switch to the huge-smp kernel it will work again.

I agree, but lsmod seys that snd-hda-intel is present. Tried switching to huge kernel. Same thing again. Although I'm not sure that I did everything well. I used the following procedure:
1. alsaconf
2. edit /etc/modprobe.d/sound
3. alsamixer
4. alsactl store
5. restart alsa

I wonder if somthing was written to some configuration file besides /etc/.../sound during first setup (with generic kernel) that should be undone?

You may need to pass an option to the snd-hda-intel module. See this post (or search for 'snd-hda-intel' in these forums for others -- I have posted in a lot of threads about sound cards, and I explained a possible solution better in some threads than in others). Note that the possible options for the snd-hda-intel module depend on your sound card. You should be able to see what chipset your sound card is with either
or
You should only need to try the options available for your chipset.

Thnx, I will check out this.

What's bugs me the most is it worked, now it doesn't :confused:

I solved it! :) But it still confuses me.

The story goes like this:

After the first Slackware installation i added the following line to /etc/modprobe.d/cound:

and it worked. After that I decided to check which parameters are necessary so I tried following:

and it worked again. So without any further investigation, I concluded that option model=lenovo is unnecessary. Following notes that I made after the first installation, after second installation i did:

and it didn't work, and you know the rest of the story. Finaly after trying model=lenovo again the sound works, but... Just to be sure I excluded model option and it works without it. Also I tried just model=lenovo without position_fix and it works!

Strange, isn't it? :confused:

Thank you guys.
