Dear everyone,
i have noticed that alas doesn't support HDVD-800 USB DAC, i can not hear anything. note that this device requires it's own driver under windows/mac.
this is my alsa-info output: http://www.alsa-project.org/db/?f=fe56e65add73248baf5307a04b6b9deb2b236004
output of pasuspender -- aplay -Dplughw:2 some_file.wav: ALSA lib pcm_hw.c:1667:(_snd_pcm_hw_open) Invalid value for card main:722: audio open error: No such file or directory
output of aplay -v -fdat --dump-hw-params -d1 -Dhw:S20 /dev/zero: http://pastebin.com/p2Daxza6
speaker-test -c2 -twav -Dplughw:S20 starts OK, but i can't hear anything/
