I use QJackCTL to start JACK with these settings: Server prefix: "/usr/bin/jackd -S --realtime Realtime box: checked Priority: DEFAULT Frames/period: 1024 Sample Rate: 48000 Periods/buffer: 3 Dither: None Audio: Duplex Input device: hw:1 Output device: hw:1 Channels I/O: 2 (for both) Latency I/O: Default (for both) This gives me a latency of 64 msec. It works. When I try to go lower, I start having problems. Another note: The input/output device names might be different. If you click on the ">" button beside the input/output devices in QJackCtl, you'll see a list of audio devices. You want the one called "USB Audio Codec", not the subdevice "USB Audio". After I start JACK with QJackCtl, I start Audacity. I use Audacity because it's much easier to use for simple recording than Ardour, and I don't need the power of Ardour for what I do. Settings in Audacity: Set your project rate to 48000Hz. Under Preferences > Device: Select Host JACK Audio Connection Kit Playback device: system Recording device: system Channels 2: (stereo). I know you're recording only a single input, but I wonder if part of the problem is trying to make the UCA202 operate simultaneously as stereo (output) and mono (input). I've recorded vocal input using a mic hooked into just one side of a stereo channel, then split the stereo track to mono and deleted the empty channel track. I use JACKD because it's the only reliable way I've found to make my audio programs use the USB Audio. If I don't use JACK, all they want to use is "Default". On my laptop, Default is the non-functional onboard Intel Audio. (Laptop's 8 years old, it's been dropped a couple of times and once landed on the corner containing the external audio controls - what can I say?) About monitoring your sax input. The UCA202 has a headphone out jack. The switch beside the input channel side turns on or off its built-in hardware monitoring. You might try turning hardware monitoring ON and plugging your headphones into the headphone out jack instead of using software monitoring. See if that meets your needs.

are you really 100% sure that audacity is routing via JACK? you're running JACK on your *second* audio interface (the USB one) On Sun, Jan 27, 2013 at 12:26 PM, Bob van der Poel &lt;bob(a)mellowood.ca&gt; wrote:

And, the original problem I had with audacity doing motorboat recording while doing playback is gone with jack. So, if that works, I'm a happy camper. Like I said, I'll have to do a full track recording playing my sax and see how that works. I'll let you all know. I think the easy thing to do would be to simply blacklist the usb audio device from pulse. Then I could just start jack for that device ... and have pulse continue to run. Save some problems since pasuspender doesn't bring back the pulse devices after it terminates. Need a log out for that (and then, that doesn't always work either and I just reboot ... just like the windows guys have learned). Anyone know how to blacklist a device in pulse? -- **** Listen to my CD at http://www.mellowood.ca/music/cedars **** Bob van der Poel ** Wynndel, British Columbia, CANADA ** EMAIL: bob(a)mellowood.ca WWW: http://www.mellowood.ca
