Most everything seems to be working, but I ran into a couple of, hopefully, simple issues: 1. The UA-101 in its full speed (USB 1.1) mode times out for both capture and playback, though its high speed (USB 2) mode is perfect. (I'm using plughw to work with 2 channels here): arecord -D plughw:UA101 -f S32_LE -r 48000 -c 2 ./file.wav arecord: main:830: audio open error: Connection timed out aplay -D plughw:UA101 -f S32_LE -r 48000 -c 2 ./other-file.wav aplay: main:830: audio open error: Connection timed out 2. I noticed with the INTEGRA-7 and the R-26, so far (with "pasuspender -- cat" running simultaneously): When I first begin playback with aplay like, "aplay -D hw:INTEGRA7 -f S32_LE -r 96000 -c 2 ./file.wav" to play a long recording, and then start capturing for a while, while that's still playing with something like, "arecord -D hw:INTEGRA7 -f S32_LE -r 96000 -c 2 ./duplex-file.wav". If I then end the arecord with ctrl-c before the aplay has finished, aplay may end in the near future without finishing the entire playback, with this: aplay: pcm_write:2061: write error: Input/output error I may try beginning the capture first, and then starting aplay, but I've run out of time for tonight. If problem two can't be fixed, this functionality is certainly better than before when it wasn't working at all. I think JACK would keep the capture and playback endpoints open, until itself closes, so it's probably a rare person like me that would even notice it. Thanks again!, Lucas
