Can someone explain to me why I cant just send data directory the the ALSA devices? Are they not character devices? % sudo cat testpcm1.wav > /dev/snd/pcmC0D0p /dev/snd/pcmC0D0p: Permission denied Aplay works fine on this file. So what is aplay doing other than just sending the file data to the device? Please forgive my ignorance, but I'm new to this and there is not a lot of intro documentation. I've seen that with simple char devices you can just read and write directly to the driver... So I'm trying to understand why this does not work with ALSA drivers. -Brooke ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
