There are two slightly different ways in which ALSA addresses sound cards. One is more directly: hw:0, the other indirectly: plughw:0. If jack cannot talk to the hardware directly (hw:0 or equivalently via82xx), it can probably talk to it using plughw:0. (If via82xx is the second card, then plughw:1 and so on.) A suggestion was made to "try -r 48000." I believe that doing this will cause a 44100 file to be sent to the card at an incorrect rate. Data need to be sent to the card at the rate of the file, but if the hardware cannot do it, using plughw is required, using the rate of the file, not the card rate. Sending a 44100 file at 48000 will cause pitch shifting upwards by about 1.5 semitones. Somebody please correct me if I've misspoken here, but this is definitely the way my Terratec EWX 2496 functions. Regards, Dave.
