I've got a USB device which nearly works with ALSA cvs-current. It's an Abit UA11, and is a pretty simple device, with one SPDIF optical in, and one optical out. I'm trying to use it with an offboard HiFi DAC. The particular problem with it is related to setting the sample rate, after being told a particular rate, the device reports a very high sample rate back (approx 128k).
Playback sort of works at this rate, using OSS emulation - it looks like the device down-samples to 48kHz. I occasionally get oopses under 2.4.21, I can't get any output from the device under 2.5.74 ("cannot submit datapipe for urb 0, err = -22"). My other USB audio device - a stereo-link SL1200, doesn't give any output on this kernel either.
I'm going to try to get the device working with 2.4.22-pre2, but I just wanted to check if this sounded like a sensible thing to do? My test hardware is a Celeron 300, on an Intel 440LX motherboard (uhci). The device works pretty well under Windows2000, and Windows98 on the same hardware (although the sample rate seems to wander about a bit, and this causes reclocking problems with one of my DACs), and I've got a setup USB trace under w98, using snoopypro - http://sourceforge.net/projects/usbsnoop/
Is this the right place to be asking these questions, (or should I go off to the usb dev lists etc.?)..
Cheers,
Tim.
