Michael, thanks for your input.

Yes - it still happens with that newer Beta of audacity.  I'm fairly 
convinced it's not an audacity problem - I'm just using that program 
because it has a stereo visual sound meter.  My experience with Skype 
with a mic plugged in was similar - very noisy and sound only on left. 
Right channel seems completely dead.  Playback is perfect.

Changing settings with alsamixer - I do have just about everything 
muted.  If I increase the "Capture" gain then the noise level is 
amplified to the point where I can max out the channel.  I could mail 
you my asound.state if that would make any sense?

Interestingly alsamixer in a terminal _does_ recognise the chip as 
Realtek ALC888, whereas Fedora soundcard detection only offered me 
ALC883.  So despite my worry in an earlier post maybe the driver isn't 
confused after all - just buggy?
