I need help to solve this strange problem. I'm using gnome 3 and pulseaudio says me the only output is 'Dummy output'. So, no sound at all.
Alsa recognizes the card but the only available channel is 'Beep' (at least, it's the only channel in alsamixer).
Here is some useful stuff:

aplay -l
**** List of PLAYBACK Hardware Devices **** [That is.. no cards listed]
The second card listed in /proc/asound/cards is a TV tuner (never used), so don't consider it.
I think is a problem related to alsa, because i have no sound at all, even in console. As I said before, alsamixer gives me only one channel (beep, operating as usual) when I select (F6) the intel card.

I've forgotten to say there's no problem in Xp (yes, I installed it to verify if the card was broken).

You may have to try OSS.

Why? I've always used pulseaudio without any problem. Is there a way to understand what happened to my system? I'd like to revert to use pulseaudio and alsa as before, if possibile. If not, I'll give a chance to oss. Any idea?

does "aplay -l" list cards as root? if so, I assume your consolekit session isn't set up correctly and you therefore don't have permissions to access the audio devices. how do you login?

I've used OSS on one machine only to find out ALSA was better for it.
Is your user part of the audio group?

No cards listed even as root. However, I login using gdm but there's no sound in console too.

Yes, I'm part of the audio group.

I .. but not me . Neither fuser nor pulseaudio -vvvv show anything useful. I suspect the problem is with alsa that doesn't recognize the audio card correctly: without an available output channel, pulseaudio can only show a 'dummy output'.

Sounds likely, if aplay -l doesn't return anything. You should figure out what you can about the audio card and ask on alsa-user or something similar.

Wow.. .. Could it be a hardware problem? I mean, something wrong with the connections. In the meanwile I'll ask on alsa-user and post here alle the news and (I hope) the solutions.

Have you backed out your kernel to see if you regain your audio?

Try reinstalling linux-3.4.9 or something like that to see if it will restore function. Hopefully you still have package file in the cache.

Hi,
I have the same problem, have you tried unloading all of your snd_ ... modules and then try reloading them? That works for me, but it isn't a good solution. I also have gentoo/funtoo Linux working and it works out of the box. There is something weird with how the modules are loaded in Arch.

Wow.. I'll try as soon as I can!

Also, I decided to switch to systemd as it appears to be working better for me now. That 'permanently' fixes the sound problem. I don't have to reload the modules to get sound, it just works.

systemd doesn't do anything different, it starts the same daemon for alsa, oss, etc.

Hi all, I also have a somewhat similar problem, I only have a Dummy Output with pulse (and Gnome 3). The thing is sometimes it works, sometimes it doesn't and it seems to be completely random... My soundcards are always listed in lspci, but even with the correct modules loaded, they aren't detected as soundcards. Using systemd too btw.

Also modprobe won't let me unload and reload the snd_hda_intel module, says it's in use.

I have no idea why it would do something like that and it is kinda annoying. The motherboard is an ASUS Maximus V Gene if that matters.

Bad news (for me). There's no difference at all using systemd. And I don't have an old kernel to reinstall.. This thing is driving me mad!

Is it in your /var/cache/pacman/pkg or have you cleared them all out?
If it still exists, pacman -U /var/cache/pacman/pkg/linux-3.4.9-1-x86_64.pkg.tar.xz

There's anything in cache. But I've found some kernels I had previously saved! With the 3.4.7 (the latest I have) the problem remains. With the 3.3.7 (the oldest), sound returns to work as usual. With 3.4.2, no sound again. Now?
EDIT:
More news! I can shutdown the pc properly now, while before it always remained powered on. I guess there's something that doesn't work with new kernels and the motherboard (remember that the sound card is integrated). Is it possible?

A stab in the dark, but I've come across the dummy output problem twice while using the distros that pair ALSA and pulseaudio, I can't remember the solution but it was quite simple. I've seen solved threads in Ubuntu and Debian forums, those might be worth a quick search.
