If so can someone let me know where? Please don't start a new thread every time you post but reply to an existing thread. Given the traffic on this list, the conversation is not easy to follow otherwise. Regarding your issue - the descriptors look sane AFAICS. Please have a look at /proc/asound/card/xxx/stream* (where xxx is the index of your USB soundcard), and report the actual streaming frequency when playing at rates higher than 44.1khz. You can also monitor the values automatically, like so: (while sleep 0.123; do grep 'Momentary freq' /proc/asound/xxx/stream0; done) | uniq Also, how to you play the audio? Try with aplay, and try to tweak the values in the --buffer-size parameters. Daniel
