Hi All: I have also been experiencing this problem for some time. I just realized that there is a newer version of Soundtap, version 6.03, which appears to solve the problem. The application file is dated Mar. 01, 2019. I was using an older version from Apr. 12, 2018. I have used the 6.03 version for several hours straight and have not encountered the problem. In the past on my system the problem would have easily manifested itself in the first 5 or 10 minutes max. I am running the program on Windows 10. Try it and Good luck!
