I have started to have issued with the sound board in my Tee'd Off. The board works perfectly for 30 mins or so until it heats up. Then, the sound starts to degrade. It starts to degrade slowly with some music or sound effects sounding off, but eventually it gets to the point where the sound distorts and most of the sounds revert to beeps and boops instead of full sound effects. I shot a video of some of the sound effects once they start to degrade:
Any ideas on where I should focus for troubleshooting?
