ALSA often doesn't produce sound anymore after suspend

Hi,

For some years this has been fine and pulseaudio worked fine after waking up from suspend.

But for about one or two month it more and more often doesn't. After waking up from suspend I just don't hear sound anymore. I can't find any error message anywhere, just that it doesn't output sound anymore. Killing it with "pulseaudio -k" or "pkill pulseaudio" or "pkill -9 pulseaudio" doesn't solve it. But "telinit 1", waiting until pulseaudio is dead and then "telinit 5" solves it so it is definitely not my sound driver.

Any ideas how I can find out what's wrong?

Maybe the power saving for my sound chip triggered the problem. I had this in my startup config:

echo 1 > /sys/module/snd_hda_intel/parameters/power_save

I have removed it and hadn't had that problem so far. If it doesn't happen in the next time I'll mark this as solved. :-/

EDIT:
Nope, it didn't help. Today after waking up from suspend it didn't output any sound although everything seemed fine.
This time I tried transferring the sound over the network with pulseaudio. That worked.
Then I killed everything and even went to init 1. But there not even mplayer -ao alsa worked and I had to reboot to get my sound back. So, not pulseaudio's fault, but alsa doesn't work right.
