First, thanks very much for trying to cover all devices through detection! I had hoped something like this could be done, but sadly, it has created a mixed result: Roland VG-99 Perfect!: arecord -D hw:VG99 -f S24_3LE -r 44100 -c 2 ./file.wav Recording WAVE './file.wav' : Signed 24 bit Little Endian in 3bytes, Rate 44100 Hz, Stereo ^CAborted by signal Interrupt... aplay -D hw:VG99 -f S24_3LE -r 44100 -c 2 ./file.wav Playing WAVE './file.wav' : Signed 24 bit Little Endian in 3bytes, Rate 44100 Hz, Stereo Roland INTEGRA-7 doesn't capture, but plays perfectly (only 96 kHz mode tested): arecord -D hw:INTEGRA7 -f S32_LE -r 96000 -c 2 ./file.wav Recording WAVE './file.wav' : Signed 32 bit Little Endian, Rate 96000 Hz, Stereo arecord: pcm_read:2153: read error: Input/output error aplay -D hw:INTEGRA7 -f S32_LE -r 96000 -c 2 ./other-file.wav Playing WAVE './other-file.wav' : Signed 32 bit Little Endian, Rate 96000 Hz, Stereo Roland R-26 doesn't capture, but plays perfectly (only 96 kHz mode tested): arecord -D hw:R26AUDIO -f S32_LE -r 96000 -c 2 ./file.wav Recording WAVE './file.wav' : Signed 32 bit Little Endian, Rate 96000 Hz, Stereo arecord: pcm_read:2153: read error: Input/output error aplay -D hw:R26AUDIO -f S32_LE -r 96000 -c 2 ./other-file.wav Playing WAVE './other-file.wav' : Signed 32 bit Little Endian, Rate 96000 Hz, Stereo Roland Boutique D-05 doesn't capture, but plays perfectly: arecord -D hw:Boutique -f S32_LE -r 96000 -c 2 ./file.wav Recording WAVE './file.wav' : Signed 32 bit Little Endian, Rate 96000 Hz, Stereo arecord: pcm_read:2153: read error: Input/output error aplay -D hw:Boutique -f S32_LE -r 96000 -c 2 ./other-file.wav Playing WAVE './other-file.wav' : Signed 32 bit Little Endian, Rate 96000 Hz, Stereo EDIROL UA-4FX Perfect!

Thanks again Takashi, Lucas
