Amancio: As per your request (slightly before Thanksgiving), I've been able
to reproduce this problem with some impunity.
I'm running vat 4.0b2 from the ports directory, listening to Charlie talk
about the new tunnel proposal for MobileIP. There's a healthy amount of
packet loss, enough for there to be skips and pops.
Symptoms:
- Whenever there's a playout deficit, sometimes I hear a pop, but more
often I hear Charlie's voice start to echo (nothing more annoying than
hearing a Southern drawl echo, YMMV)
- When the playout deficit goes beyond 1 second, the DMA output timeout
messages begin. The solution is to kill vat and restart it. PITA, but
it works.
My current is current from about Sunday night, with the ld.so fixes in it.
Hope this helps.
