After I installed SoundTap v 2.31, I started getting this message, "Waiting for an audio stream to record." The other messages are, "Successfully connected to driver" and ":Recording mode switched ON." However, SoundTap is not detecting an audio stream. I have a new Dell Inspiron 3647 that I bought on Aug. 16, 2014. The computer is running 64-bit Windows 8.1, and has a 4th-generation Intel Core i5 with a Realtek High Definition Audio sound card. This driver version is 18.104.22.16816, dated Aug. 13, 2013. Is that the cause of the problem? Thanks.
