It's a known problem I forgot, but this doesn't matter much.

Did you notice the problem with other applications, too?
When you wrote "The sample plays for fraction of a second than stops.", it means that the speaker-test program stalls? Or it's shorter playbacks?
Also, please test booting with snd_usb_audio.lowlatency=0 boot option. Does it behave like before again?

I'll need to test my device at first. Maybe tomorrow.
