There are still the issue of samples dropping.

Tto reproduce it:
- Open Audacity and set it up to be using Jack.
- Click Generate -> Tone -> Ok.

"Normally" you should hear very regular pops...

JFTR: In the past, audacity wasn't exactly the most reliable piece of
audio software available. It was actually known to be broken in
different ways every time a new version was available.

I've seen so many bug reports against audacity (as a member of the
Debian Multimedia Package Maintainers) and spent some hours hacking
patches that I arrived at the conclusion that audacity is best for
visualizing waveforms. I guess it was never intended to actually output
them. ;)


Long story short: just because audacity behaves abnormally doesn't mean
the card itself is broken.

Or more frankly: audacity isn't reliable enough to be used as a test
tool. Use plain jackd and maybe ardour to record a track via digital
loopback. Maybe even remove jackd from the test setup.

I wonder if you're just seeing ordinary xruns caused by wrong jackd
settings.

Unfortunately this isn't an Audacity bug. It's reproducable with any 
synth or playback software etc. that I have tried. Moreover, by going 
back to a very early version of the FTU support you can play back at 48 
kHz and 96 kHz sampling rate without those clicks.
