OK so I grabbed a new VAST FMT-212R this year and I have some intermittent noise issues. I set the frequency with a PC via the USB config software, that seems to work OK. However, when the show is running I get intermittent parts at various sections throughout my display where the FM transmission has really noisy audio and the only fix I have found so far is to open up the my FPP web interface and touch the volume slider (either up or down, direction doesnt matter) then the audio fixes itself until the next intermittent time it decides to go spastic. Anyone experienced this before or have any suggestions? I have tried playing direct to it (ie. selecting it as the output in FPP settings for audio), or using my usb soundcard that I used last year and running a 3.5mm aux lead from it to the transmitter, both yielding the same outcome.
