Terrible sound when trying to record a file

Been trying to record a tune off youtube, ok until hit the start monitoring and then the sound coming off the track throo the monitoring changes to a tinny, screeching, unable to make sence of the track. The timeline also takes up the whole line height so looks like something is set too high and the software cannot deal with it…Any ideas please?

I thought the problem was sorted but no, I now have the ‘start monitering’ back, but when press record the time line shows ‘flat lined’ all the time with a very faint noise instead of the music. Any ideas please.



WASAPI is the best quality option for recording from the internet,
but recording will only begin if there is sound to record.
