But I only paid $5 for my Yamaha. :-) Actually I pulled the AW35/37 (the cheap one) as the sound it produced under FreeBSD was badly wrong. As if it were running an ADPCM codec and being fed PCM or something. Spent a fair amount of time admiring the documentaion and trying my hand at hacking things into the driver. There was an init sequence I think was wrong but my work neither improved or hurt anything so I abandonded it. Bought the Yamaha card. It played! It sounded terrible. The AOpen card claimed CS's standard 85db S/N ratio. The Yamaha S/N ratio was about 10db according to my ears. They can't all be as bad as mine else Yamaha would get laughed into oblivion. -- David Kelly N4HHE, dkelly@hiwaay.net ===================================================================== The human mind ordinarily operates at only ten percent of its capacity -- the rest is overhead for the operating system.
