Hi All. I have Win 7 home, my PC is 64 but I still use 32. Very basic use of BiaB to make back tracks (MP3) just to sing along and strum the guitar. I have not used RB much. Installed 2019 into the same setup. I'm not very computer wise. BiaB is fine and quiet but as soon as I open RB I am getting a very high pitch whine, constant pitch and volume. Never noticed this on 2018. When I close RB it's gone. Can't work out what this is about. I have tried to make a track for "Memories are made of this", and wanted to try and record a bit of backing vocals (Sweet ,Sweet, the Memories you given me). The whine is a bit irritating but does not get recorded into the audio. Ideas please?
