[ardour-users] Recording seems fine, playback not at all

[easy rider]

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:
jackd -R -d alsa -r 44100&ardour
and I can record.

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.
What I'm using?

I don't know if these types of messages are meaning anything. USB device of
course allowed in BIOS...
