Yes, you are right. But this configuration wasn't successful too.

Thank you for advice, but machine running FreeBSD is slow... I better have fast 
system with gcc2, which occupies less space, than system with gcc3.4, which is a 
bit more heavy, but where sound works (if it is really so). :-)

Well, and why can I get such messages:

pcm0:play:0: play interrupt timeout, channel dead

? What can be wrong? Sound card is detected, IRQ, DMA, port are right. I've 
found some similiar problems in Google, but solutions from there didn't match my 
case.
