Hi! I own an ASUS A7V266-E motherboard with onboard-sound. With this kernel: FreeBSD zerogravity.kawo2.rwth-aachen.de 5.0-CURRENT FreeBSD 5.0-CURRENT #1: Thu Dec 20 00:34:04 CET 2001 alex@zerogravity.kawo2.rwth-aachen.de:/storage/zerogravity/obj/usr/src/sys/CICHLIDS i386 Sound works fine, as it should (ok, I can't get line-in/mic to work, but that's another issue). alex@zerogravity ~dir $ cat /dev/sndstat FreeBSD Audio Driver (newpcm) Installed devices: pcm0: <CMedia CMI8738> at io 0xd800 irq 10 (1p/1r/0v channels duplex default) With a kernel starting January 18th or so I always get a cracking noise on tones with high loudness, e.g. on MP3s with much bass. I can't see any changes to the cmi-driver in that timespan, though, so I wonder what might have changed. Any idea?
