Thanks for your prompt reply Dave.

The problem was Pulse Audio, as I suspected. It wasn't enough to just  
disable pulse audio in the sound settings, I had to kill the resulting PID.

Now another problem has surfaced; there is a ticking sound in the 
background of the transmitted sound. Again, this is a problem that I 
had previously encountered and the cure was to buy a different sound 
card. However, this option is not viable in the case of a laptop.

I don't know what effect this ticking sound will have on my transmitted  
signal (I've recently returned to Amateur Radio after a lengthy break 
and need to construct a suitable lead) but I'm sure that I can do without 
it.

Again, can anyone offer any suggestions?
