Two URBs is the Jack buffer size, isn't it? Does Jack complain? James, pleasy try running aplay and arecord at the same time; something like this: aplay -D hw:x -t raw -c 4 -f S32_LE -r 44100 --period-size=128 --buffer-size=256 /dev/zero & arecord -D hw:x -c 2 -f S32_LE -r 44100 --period-size=128 --buffer-size=256 test.wav Regards, Clemens -- To unsubscribe from this list: send the line "unsubscribe linux-usb" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
