I'd like to use my -STABLE system for recording line-level audio, leaving the A/D conversion to something *other* than the crappy A-D conversion done by most sound cards or motherboards with built-in sound. I've searched the freebsd.org mail archives to see whether anyone's been able to record with any sort of USB Audio device (using uaudio) and it doesn't look good. Another option is that the motherboard I've currently got in my workstation in the office claims to support S/PDIF in, so an offboard A-D converter might work - but I have no idea whether the S/PDIF in is actually supported or not, nor what bitrates it'll understand. Here's all dmesg tells me: pci0: <unknown card> (vendor=0x8086, dev=0x24c3) at 31.3 irq 5 pcm0: <Intel 82801DB (ICH4)> port 0xe400-0xe43f,0xe000-0xe0ff mem 0xec182000-0xec1820ff,0xec181000-0xec1811ff irq 5 at device 31.5 on pci0 pcm0: <Realtek ALC650 ac97 codec> Right now, though, I can't even get this card to record off the mic in. Sigh. Plays fine, though. My Sony Vaio laptop can record from the mic, but only mono. Its dmesg says: pci0: <unknown card> (vendor=0x104d, dev=0x8039) at 8.0 irq 9 pcm0: <Yamaha DS-1E (YMF744)> port 0xfc8c-0xfc8f,0xfcc0-0xfcff mem 0xfedf8000-0xfedfffff irq 9 at device 9.0 on pci0 pcm0: <Asahi Kasei AK4543 ac97 codec> Anyways, recommendations/suggestions welcome. Brian
