I haven't done a serious comprehensive test to try recording or anything; that comes later. > Last time I tried my USB audio device I got pretty reliable panics trying to > get KDE to use it :( Which FreeBSD and what sort of device? My FreeBSD-4.x is using as much USB code from -current as possible, which might make some difference. The uaudio device I have is one that I inquired about some months back in either the -multimedia or -hardware list -- I need to dig out that post, and make a followup to it with potentially useful info sometime later today. There are, um, ``interesting'' things I've observed, which I'll mention in my followup to whichever list, that I need to verify are independent of UHCI/OHCI controller, and also whether afflict NetBSD as well. NetBSD also gives me more access to the device. FreeBSD finds it as uaudio and uhid, and (my module source) plays back at a fixed volume level (apparently samplerate too). The (usual) worst I experience is the `isoc TD' message followed by a `pcmX:play: timeout, channel dead' type of message, after which the device no longer works. While I've had panics from other causes, I don't think any of mine could be pinned on the uaudio/uhid device -- but I haven't done much in the way of connect/disconnecting and stuff. thanks barry bouwsma
