Hi there,
I think I can help you a little here with my knowledge.
You should update your old PC with the latest sound drivers. I know it can be a little costly but to get something better in return we need to invest a little by our side too. Or you should try disabling and enabling a process for your audio driver. If this too is not working then contact TheCompuLab team as they can help you solve your problem. You can check Broward Computer services here or if you want to explore information on Google. Hope this will help you.
