Feedback/static in recording, intermittent
I am experiencing a strange issue when recording with Ardour. We are recording 3 microphones (Audio-techinca AT2020 USB), each on a separate track, and everything will be going along skippy. Randomly I will hear what sounds like feedback and an echo in the monitor and when I watch the waveform I can see that the sound is coming in twice. It seems to come in partially each time and almost seems like an issue of the information being captured in Ardour correctly. It is quite literally repeating everything and it effects each track.
We have had this happen on several machines in the past though it was a rare issue that was solved by a restart of the program. We have started to use a new computer and now it consistently happens every time, sometimes almost immediately and sometimes after 15-20 minutes of recording. I have tried adjusting the latency on both Ardour and Jack to see if that would fix the issue but it doesn't seem to have an impact on it. I have started Jack before and after starting Ardour as well as not launching it at all with no change. Does anyone know what would be causing that to happen? I am on a brand new computer so it could be a system setting but I have gone everywhere that I would normally look and simply can't diagnose where its coming from. Please help.
