Run speaker-test -c2 -twav Do the test to each sound card with alsamixer set to 0dB for most controls accept the master, and leave the master at a sensible setting for your setup so that you can hear sound at a sensible level With the same dB values on the Andigy 2 and DMX, do you get the same loudness of sound output to the speakers? I would like to find out if the problem is in the playback path, or the capture path.
