This is driving me mad. Every time Express Talk rings, it sets the system sound output to "Internal Speakers" (I'm running it on a Mac Pro).
If I answer the call, the sound output switches back to Line Out, as selected in ET's Options.
If I don't answer it and let someone else in the office pick it up, my sound remains on Internal!
I cannot figure out how to stop the app doing this, and it's driving me nuts.
Any ideas?
