Windows 7 Audacity 2.1.0
During recording I will sometimes encounter random changes where the recording swaps from a two track recording to only the left rack. It will return to a two track recording. This results in parts of my audio only playing form the left speaker. There appears no trigger.
There is only one audio a blue yeti microphone.
Probably the first thing to try is recording at a more sensible default sample rate. Yeti is designed to record at 48000 Hz http://www.bluemic.com/yeti/#/specs/. You’re expecting the computer and the USB stream to handle four times more data than it needs to by choosing 192000 Hz, for no comparable gain in quality.
