Hello .. I have just been sent an LG S1 laptop and I have installed arch on it successfully. Only thing is, main speaker doesnt work. I know its functionnal, cause I had heard it from the initial vista install. Now, the headphones jack does work. And also, I use to own a very similiar but somewhat lower end model, the LG T1, which uses basically the same drivers and all, but the sound did work on that one.
Now what worries me a bit is that from time to time ill hear odd crackling sounds from the speaker. At one point, when I was trying to make XGL work with KDM, it did it to the point I thought my laptop was gonna explode.
Anyway, the fact that the speaker doesnt play sounds I can kinda live with, might just be a configuration issue; the crackling sounds howevevr, even though they rarely happen are like nothing ive ever heard or seen or whatever and they kinda worry me. ..
any ideas guys ?
(the best way I can describe it would be like what an "explosion" sound on an old nintendo or other 1980 game console sounded like.. like a broken up saw wave .. very odd)

Hmm, I also have a weird issue for a few weeks, but I have no idea if it's the same :
the first time I play a sound after booting, I get a big but very short crackling sound from my laptop. After that, it plays just fine, like before.

yeah I just read this other post http://bbs.archlinux.org/viewtopic.php?id=37031 and im starting to think something might be up. Maybe this is also similar to what you're experiencing ?
Also, if it help, I have checked with lshwd my audio device and it is an Intel "io controller hub high definition audio (snd-hda-intel), and lsmod reports the proper modules are loaded.

Oh thanks for the link, I'm still not sure if your issue is the same, but that's definitively mine.
But since you're also using snd-hda-intel, it's probably the same.

I suppose you already tried to downgrade alsa and kernel packages, right?

nope, i just dont think that is a viable solution. it may be a fix, but not a solution to the problem. have you tried doing this? if not i guess i *could* try it when i get back on my computer but id much rather there be a true solution.

again if it means anything, I had an LG T1 not so long ago with relatively the same hardware for audio and I don't recall kernel 2.6.22 causing any problems. Only booboo with that one was that pluggin in headphones did not shut off the "external" speaker.
Now, since then I have gotten this new S1 model because the T1 had an unresolvable LCD screen issue and I got screwed by the vendor and its long story but they sent me this much higher end model, and the sound doesnt work on that one - but I cant compare with previous kernels because none other have ever run on this one, and I cant compare also because its not the same machine.
But like I said, the T1 and S1 probably have very different main boards, but the sound "hardware" is supposed to be the same - and one the T1, Im pretty sure that 2.6.22 gave me the sound I wanted.
Guess ill try downgrading later see if it works ... right now im planning a move to 64 bits anyway, and am waiting for the newer ati fglrx with AIGLX support to be released to do so ..

sorry to bump this _horribly_ old thread but someone in IRC pointed me to a solution. it has recently been put on the alsa wiki page as well. add
options snd-hda-intel power_save=0
in /etc/modprobe.conf then unload and reload the snd-hda-intel module. all is well on my computer now.

Cool, thanks for the tip, I'll try that.
Although that's probably just a work around, isn't it? Why does waking up the chip cause these cracklings?
Are there any upstream resources about this problem? (alsa wiki, ML, bugzilla,..) ?
