Hi,
I've a similar problem on my IBM X31 with my USB DAC (a StyleAudio
Carat-Peridot) using mplayer with the libsndio backend. The audio
stutters and crackles a lot, but only when playing movies. If I play
audio files, if I use the sun audio backend, or if I use the integrated
sound-card of my laptop, everything is fine.
When I plug the USB DAC, I see the following lines in my dmesg:
uaudio0 at uhub2 port 1 configuration 1 interface 0 "Burr-Brown from TI USB
Audio DAC" rev 1.10/1.00 addr 2
uaudio0: audio rev 1.00, 2 mixer controls
audio1 at uaudio0
uhidev0 at uhub2 port 1 configuration 1 interface 2 "Burr-Brown from TI USB
Audio DAC" rev 1.10/1.00 addr 2
uhidev0: iclass 3/0
uhid0 at uhidev0: input=1, output=0, feature=0
So I use mplayer with the following command
env AUDIODEVICE=/dev/audio1 mplayer my_movie.avi
I tried to use "aucat -l -f /dev/audio1" but it doesn't work and ends
with the following error:
/dev/audio1: Device not configured
safile_new: can't open device
Here is the full dmesg:
