It is possible that there is electrical cross-talk within the audio interface of your laptop. The audio design built in to laptops prioritizes low physical space used and low cost over high audio performance. > I did attempt to repeat my experimental recording on my desktop > computer, but couldn't figure out how to get the input from my webcam's > microphone into qTractor.

The internal timing of jackd is tied tightly to the audio sample timing of the audio interface, so using two separate interfaces does not mesh well with the design philosophy. To use a second interface you need software which re- samples to cross over between the independent clock domains of the two audio interfaces. If using jackd v2 version from the last year or more there is a built-in internal client for using a second interface, or you can run zita-a2j from the zita-ajabridge package as an external jack program to do the same thing. -- Chris Caudle _______________________________________________ Linux-audio-user mailing list -- linux-audio-user@xxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to linux-audio-user-leave@xxxxxxxxxxxxxxxxxxxx
