I already had pcm in my kernel. It's working, but there are some Strange Things Happening. Firstly, here's /dev/sndstat: FreeBSD Audio Driver (newpcm) Jan 5 2001 12:50:04 Installed devices: pcm0: at io 0xec00 irq 16 (1p/1r channels duplex) (Aside: is that really the chipset on the Soundblaster 64?). I get kernel warnings since I installed the card: Jan 14 13:00:15 sunrise /boot/kernel/kernel: pcm0: hwptr went backwards 2112 -> 1888 I'm using FreeBSD Current, built on 5 January 2001. What I've got is some very strange sounds when I run mpg123 on a standard MP3 file. It's going through /dev/dsp and appears to play the samples at a very slow speed, with weird echoes. It's like a special effect. Using the -a flag with mpg123 allows me to play through /dev/audio, which sounds right except that it's distorted. At all volume levels, the audio sounds overdriven, and I know this is not due to impedance mismatches or faults elsewhere having used the card in Linux with the same cabling arrangements, amplifier etc. If this is a known problem, I'll stop for now and watch out for fixes. If it's not the expected behaviour from the PCM driver though, can anyone advise?
