[alsa-devel] Subject= @Daniel Mack: Send you a FTU
I saw on the mailing that you a Felix have been doing a great deal of work to provide better support for the M-Audio FastTrack Ultra. I tested yesterday the new patch that provides mixer and the possibility to change the internal routing of the soundcard... I can finally use all the input/output to use external FX, that's very handy!
Anyway, on the M-Audio forum, Felix has been mentionning several times that there were few bugs that needed to be fixed with this soundcard, but that you needed to get your hand on one device to fix them (and may be even improve things around its support in general).
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.
Cheers

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.

Felix
