I'm afraid it is a complex change to do into OPAL in order to allow
sound events to be played on the same stream than the audio
communication stream.

I only see 3 solutions to that problem :
1) Modify Ekiga and OPAL in order to allow that
2) Fix the driver so that it is responsive enough
3) Disable sound events

The easy fix for now is 3).
The hard fix is 1).

I really suggest the driver to be fixed. I could also look at a solution
for 1), but given the amount of work required, I don't think I will have
the time before a few months...
