Hi, I've recently installed "64studio" Linux distro on my AMD64
machine, use EDIROL UA-20 usb soundcard. I have modprobed
snd-usb-audio, seens working fine, no error messages. I start Ardour
with jack:<br>
jackd -R -d alsa -r 44100&ardour<br>
and I can record.<br>
<br>
But I cannot hear a thing while playback. Not only here, also with
Audacity running without jackd - also can record (I see the
visualisation reacts ok), but not to playback. Where am I wrong? Seems
like there whole of playback is wrong. Audacity shows me graphicaly the
output level, but - no sound. In prafferences of course
Input/output=/dev/dsp. The card is OK - I have checked it on Windows.<br>
