Actually I found some chipsets (e.g. opti931) where there is apparently a bug (either in the chip or in the driver, but i suspect the former) and you cannot select a compressed mode (ULAW) on both play&rec; because the MSS driver defaults to use the same mode for play&rec even if you use half duples, this might cause problems. However the 4236 and 4237 work perfectly fine. cheers luigi To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-multimedia" in the body of the message
