Yeah, xruns - that's the one. If your system isn't configured forlow-latency work [1], you usually get a lot of them until you set bigbuffer. Can you test with bigger buffers?
I believe (and I would like to confirm that it's not just me) thatcard works perfectly on 48000 and not so great on 44100 regardless ofwhat is set as samplerate in alsamixer. I can get 2ms on 48000 but Ican't get 50ms on 44100. It's weird because this card should supportboth samplerates equally.
However, it gets even more weird - if you use just capture or justplayback at 441000 it works normally. Only duplex breaks on 44100.Yet, duplex works on 48000.
If you can test this on your card I would be very grateful. Again,sorry for going off topic.
I'm also sending a copy of this mail to James in hope that he will beinterested to know this.
