I heard one cry out "mum"!!! and then some sobs and moans...
I've been mucking around with the sound channels.
Started with 32,(default) then moved up to 128, had a lot of stuttering, (not sure what is to blame, server/arty/with music ???)
Dropped down to 64 channels and seem to have found some stability.
I'm sticking with 64 for the time being.
X-Fi Gamer sound card.
W7 64 bit.
