Theres nothing to twig - SSB has been attempting the odd windup for the last year. Its hardly subtle. When it occurs I just correct his statements and hope he gets bored. I have also noticed that when someone starts a windup you always seem to jump on the bandwagon. Not necessarily SSB.

Now lets get back on topic.

Yes the problem is the virtual configuration of the sound card. I am buying either a new sound card or a usb mic preamp. As the recording seemed to work I thought it was ok. I soon figured out it wasnt however - all part of the process and worth posting. Especially as it coaxed out your comments based on an erroneous plot

I am sure ssb is a fine fellow but he overrates his success at winding me up. Moving on swiftly...
