WAV file save problem

I am having trouble recording and saving to file. During continuous recording the fluctuant wave keeps cutting out then deleting previous material and starting again. This happens several times during a session but does NOT interfere with the live turntable playback which is audible throughout. At the end I couldn’t save any material to a WAV because no recorded material appeared to be there to save in the file. Meanwhile the audio play was working fine throughout. Presumable this is happening because of settings on my computer. Please advise ASAP.

Does any of this sound about right?


Audacity has to run in real time, no waiting around for hard drive space to free up. Erratic or skipping is usually Audacity trying to keep too many balls in the air at once.
