I know you developers are overloaded, but here are a few things I've discovered as I attempt to diagnose the problem..
After installing the Audiophile once on a Windows machine, MIDI works with 0.9.5, even if I power off and unplug the unit from USB and AC. It seems that the firmware only has to be loaded once. I get sound (but always at 48khz) with 0.9.5 iff I do the following: 1. make sure ALSA modules are unloaded 2. unplug the audiophile from the computer 3. plug the audiophile into the computer snd-usb-audio and other modules are loaded automatically. --However, MIDI doesn't work if I do this. If I load the ALSA modules any other way than the above, MIDI works, but audio is either static or distorted. I also get a bunch of these in /var/log/debug when I play a sound file (44100 Hz, 16 bit, stereo) with aplay: Jul 17 01:14:32 purebox kernel: usb.c: usb-check-bandwidth would have FAILED: was 938, would be 940, bustime = 2 us Jul 17 01:14:32 purebox kernel: usb.c: usb-check-bandwidth would have FAILED: was 826, would be 940, bustime = 114 us Jul 17 01:14:32 purebox kernel: usb.c: usb-check-bandwidth would have FAILED: was 938, would be 940, bustime = 2 us Jul 17 01:14:33 purebox kernel: usb.c: usb-check-bandwidth would have FAILED: was 483, would be 940, bustime = 457 us Jul 17 01:14:33 purebox kernel: usb.c: usb-check-bandwidth would have FAILED: was 938, would be 940, bustime = 2 us Jul 17 01:14:33 purebox kernel: usb.c: usb-check-bandwidth would have FAILED: was 826, would be 940, bustime = 114 us etc. running tail -f /var/log/debug shows that 10 of these lines are spit out per second during playback. They don't appear if I let the modules load automatically.
