Hi!
Quite frankly, I'm not fully aware about known issues with these devices that need attention. Could you summarize which problems are left to look at?
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.
