This works for me arecord -D hw:0,0 -d 5 -f S16_LE -r 48000 -c 2 test.wav Recording WAVE 'test.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Stereo root@pbp:/tmp/snd# ^C Do you really have 6 devices on card 0? And I don't know that I've ever seen a 32 bit wav file, 8 is often enough. Need to specify # of channels I think like -c 2. But I copied your line and started hacking it until it worked. The error message could probably be more informative, like which argument does it have a problem with.
