Thanks for the previous email........However although I can see that the stereo mix is working, and checked that the playback and recording devices are as you stated I am still unable to get any sound from the computer speakers.......Even if I unplug the turntable from it's USB port I am still unable to hear any sound on playback, also I am still unable to get any sound from any other programme within my computer.
 
Can you please help further.
Thank You
Graham Bunn.
