Hi John

I must admit I re-installed PA once I found out that uninstalling it 
hadn't rectified the ARdour problem, because I wasn't sure what else it 
might bugger up!

Thanks for the tip. I've checked by looking at Envy24 and by arming 
tracks in Ardour and it seems that all four channels of my Audiophile 
24/96 are working as expected.
