I'm joining the growing crowd of Linux users having trouble with audio. No sound at all on this Gateway P6860FX (?) laptop running x86_64 Arch. It used to work. I don't use audio everyday, so can't be sure when something changed. Prime suspect is a run of pacman -Syu between when audio worked last week and when it didn't a couple days ago.
Please see http://pastebin.com/m71f85066 for output of aplay -l, lsmod, and so forth. A few bits are below.
* using external speakers. known good; works fine with other audio devices.
(tried unplugging them, but no sound through the built-ins either)
* ext. speakers _are_ plugged in, have power, volume up, no beer spilled upon, etc.
* yes, all alsamixer levels max up, unmuted
* audio is Intel 82801H
* alsa version 1.0.19 (lib,utils,...)
* linux kernel 2.6.29
* ran alsaconf several times, before and after attempts to fix
* audio players and editors e.g. audacity show waveforms, VU meter activity
* googled for similar trouble. no successful solution found so far.
many turned out to be silly oversights, card not detected, solutions that involve settings i already have, etc.
* experimented with model param in /etc/modprobe.d/
* tried rebooting, reloading kernel snd modules.
speaker-test appears to run fine on command line, returning to the bash prompt after expected number of seconds, and prints no error messages, but no sound at all.
Other tests i run are firefox on a known good website using flash with sound, aplay on a known good .wav or .mp3 file, and vlc on a known good video file. Sometimes, i get a system beep when backspacing at the start of a command line. More often not, since it's annoying so i turn it off.
Although the jackd software is installed, it is not running or involved in any way. OSS is not installed. snd_pcsp, blamed for trouble in some of the googled info i found, is deactivated (but i could be wrong).
Overall, the problem is as if all the software is working fine but the speaker isn't plugged in. Except, it is indeed plugged in to the computer.
Ideas for solution or at least further diagnostics?

Problem went away after running LILO and rebooting.

I have a similar problem, but reboot can't help me.

there isn't "options snd-hda-intel model=" in the files, because alsaconf didn't put it into the files
how can I get to know which model do I need to use?
what is the different between the lines in modprobe.conf and in modprobe.d/sound?
I have no sound since an update before some days.

i commented out my options lines from yesterday's experimenting, and sound is working, so looks like the options aren't needed.
Being in electronics, i've witnessed this happen often: "Is it plugged in?" "Yes." "You sure?" "I double checked. Still not working." "Are you _really_ sure it's plugged in?" "Um, oops, wait it's not plugged in." It was like that with the alsa sound problem, al. checking again if alsamixer had the relevant channels unmuted and cranked up. Also, i literally had to be sure it was plugged in - the speaker power plug, that is, which is a cheapo brand that falls out sometimes.
barii - It's not clear if you did run lilo or not, or grub, after the update.
Odd discovery i made after the sound worked: if i unmute channels labelled "Analog" the sound goes away. These must be kept muted, apparently. Who knows how much time i spent with things unwittingly set correctly, but didn't know it due to having Analog unmuted...

I use grub, so I think that I needn't run grub aflter that, do I?

I have read. It isn't work when headphone checked on or off
and kde mixer told that it isn't work
when i start a viseo/audiio player, i get it:
KDE deteched that one or more internal sound devices were removed
do dou want KDE to permanently korget about these devices?
this is the list of devicesKDE thinks can be removed:
Capture: HDA Intel (ALC885 Analog)
Output: HDA Intel (ALC885 Analog)

OK:)
I switched off Analog Loopback, and now everyting is ok
I can't believe it

Egads - that worked for me too! Oh man, what a relief - I can't believe it! I've been wrestling with this problem for months.
I'm not even sure why "analog loopback" was being set (or why it's being set automatically every time I boot up) - but as long as I know how to fix the problem who cares!
