I've been happily using the line6usb driver with my POD XTLive and Ubuntu Studio. Recording with Jack and Ardour 2.
I appreciate all the work that you've been putting into this.
I'm having a problem and I'm not sure if I'm the only one or if others have it or have found a solution to it.
While monitoring the playback in order to do overdubs, at random there will be a blast of white noise in the headphones. it doesn't come up in the audio track unless it bleeds from the headphones into the microphone. But the blast is at the highest volume which makes dubs difficult to do. Right now I'm trying to do some multitracking with my kids, and the blasts are freaking them out.
As far as I know, the blast only happens during playback and overdubs, it's loud, it happens at random, it last anywhere from a fraction of a second to 2 or 3 seconds, it doesn't show up in the audio track unless it bleeds through the microphone which makes me think it has something to do with the hardware.
I've tried googling around about it in the Ardour forums and some people suggest changing the sample rate, but that's not possible with this hardware/driver setup. So any other thoughts or clues would be greatly appreciated.
Thanks!

I played around with it to see if I could *cause* the bursts and maybe that would give me some insight. I could. Whenever I moved the mouse around a lot or dragged windows around the screen quickly, I could make the bursts happen faster and longer.
That inspired me to try turning off Compiz-Fusion.
I simply went to System > Preferences > Appearance and set the "Visual Effects" to "None" and was not able to recreate the white noise bursts.
Tomorrow I'm going to do another recording session with the kids and hopefully the bursts will be gone for good.

Please make sure that:
*) you are using the most recent version of the Line6 USB driver
*) you are running jack with realtime priority (the mouse interfering with audio output indicates that jack might not have sufficient priority)
Kind regards,
