Playback bugging for two days

The voice recording and playback works fine for a few minutes, then after a while it stops replaying the recording samples. I like to replay each one often to compare tracks and get the perfect one. The recording is saved, it is just muted when I try to play it. Restarting the program fixes it and they all play when I reload. But then after about ten minutes it starts bugging again. Makes it more challenging to do my voice recordings. This has never been an issue before. It started two days ago.
