Rutger,
I thank you, I now have hope that mine will work :) (yep, it's a Teac UD-H01).I do not have pulseaudio. I play directly from aplay or mpd.
I do not know if a .asoundrc or /etc/asound.conf config file is needed, I have tried many with no fix.
I'm using the latest version of alsa (1.27.2 iirc).
I play only 16bits files (all my music is lossless), 44.1KHz
If you have an alsa config file, could you paste it please ?
I've had a look at the thread you speak about, that's how I knew that the Teac can work at 16/44.1 but there are no explanations of the configuration to set in order to make it work... Hope you understand what I mean.
First of all, gonna install Fedora 18 with the same kernel as you and disable pulse, then use aplay, and I will know if it's ok.
Yours sincerely,
Eric

Dear Eric and list,
I have a Teac UD-H01 (I assume that you are talking about that one). It
works fine at 16bits/any frequency but I have crackles (much like you
are reporting) in 24bit mode (at any frequency over 48kHz). I am not
much of an expert (in particular, I'm at loss concerning 24 bit
playback) so I am not sure I can help.
In any case, the 16 bit modes worked "out of the box" on Fedora 18
running a 3.11 series kernel, on USB 2 as well as on USB 3 ports. I did
learn though that pulse-audio can be a pain when testing your interface:
it will transform any stream to a default format so you never know
exactly what your DAC receives. The upshot is that you should test
things using aplay, after disabling pulse. If you are already doing this
you may have a look at the thread "teac UD-H01, bad 24 bit playback" for
details. If your problem persists when playing a 16 bit file through
aplay, we could try to figure out in what way your setup differs from
mine.
Best,
Rutger.
