I have two issues with capture right now: 1. If I do something like: arecord -f dat -D hw:0,1 -d 5 foo.wav it seems to record for much longer than 5 seconds. In fact, "time arecord..." tells me that it goes for 10 seconds. If I then try to play back the result with aplay: aplay foo.wav the playback is too fast. The same thing happens with the -f cd format. I thought I'd try forcing mono recording but: [n8gray@golux alsa]$ arecord -D hw:0,1 -c 1 -r 48000 -f S16_LE -d 5 foo.wav Recording WAVE 'foo.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono arecord: set_params:833: Channels count non available 2. Is there a way to make the OSS emulation use hw:0,0 as the playback device and hw:0,1 as the capture device? Here's some info: [n8gray@golux alsa]$ cat /proc/asound/version Advanced Linux Sound Architecture Driver Version 0.9.7a. Compiled on Oct 1 2003 for kernel 2.4.21-0.16mm-mdkcustom.
