ALSA stopped working - no error messages [SOLVED]

The title should describe the situation well enough - everything looks like usual, no error messages appear when sounds are played, but - I can't hear them, although yesterday everything worked perfectly!

I use gentoo-sources-2.6.15-r1 and built-in ALSA. My mixer levels don't seem to have changed since when it worked.

The reasons I could think of why sound broke:
- I see "Rebuilding dependency info" when starting up/shutting down the computer, and I cannot remember to have seen this before [EDIT] Remerging baselayout solved this issue
- I updated GCC to 3.4.5
- Apps I recently emerged: busybox, ivman?

Any ideas?

[EDIT]
Another problem I noticed recently is that some processes don't terminate correctly; for example timidity or ntpd:

Please help me, tomorrow I don't have internet access anymore! If I shall post any system information, please ask now!

Besides, the timidity/ntpd problems have gone after a revdep-rebuild.

I am having exactly the same problems. No idea what happened to my machine. Sound stopped working from one day to the next.
Is it possible that a dummy sound device is being created? If so, how would i check this?

Try using user space driver.

Oh, I see you have created your own thread!

Setting up alsa-driver (latest unstable version) and unmuting channels afterwards didn't help. This makes me mad! I bet any update has made the sound malfunction!

My hardware: AMD64 system, lspci returns "05:06.0 Multimedia audio controller: VIA Technologies Inc. VT1720/24 [Envy24PT/HT] PCI Multi-Channel Audio Controller (rev 01)".

I feel stupid ... :oops:

I mixed up muting and unmuting, so I muted everything after installing alsa-driver -> no sound.

Now, having unmuted everything, it works perfectly!
