Unfortunately, this is not currently possible. I agree it would be 
useful for clients to know if samples have been dropped.

I guess the ideal thought is since that on overflows, the internal 
timing in PulseAudio changes so that this should not happen again, so 
this should not concern clients. However, what happens in practice is a 
different question :-)
