Same here; a good way to produce these symptoms is a portupgrade -a. I
only use the pcm0 card, don't know if pcm1 is affected. This is an SMP
box, if it matters.
FreeBSD Audio Driver (newpcm)
Installed devices:
pcm0: <Creative EMU10K1> at io 0xcc20 irq 21 (4p/2r/0v channels duplex
default)
pcm1: <Intel 82801BA (ICH2)> at io 0xb800, 0xbc40 irq 13 bufsz 16384
(1p/1r/0v channels duplex)
