I assume you mean that /proc/interrupts entry does not increase anymore. So Yes, it certainly sounds like the interrupts are broken. Whether this is something in the sound card driver, or a hardware fault on your machine is hard to say. What happens if you unload and then reload the sound card driver, instead of rebooting. Ie, stop whatever is using the sound, and then use rmmod to unload the sound card driver, and then reload it. Does the soundcard work again?

Well, sound is hardly a kernel crash or instability. > >>> I have tried an other soundcard, but that did not help. What do you mean "that does not help"? You removed this soundcard and installed a totally different brand of soundcard? You left this one in and used some other eg onboard soundcard? >> >> I see.

What do you need to know to help me here? You could of course try alsa 1.0.15 instead. Make sure you have your kernel-source installed in /usr/src for your current kernel, and have gcc installed, download the alsa-drvers go into the directory and do ./configure make make install which should install the new drivers. >> >> Well, that sounds modern.
