I am afraid things don't look much better. My current multicast traffic feed is not the best and that seems to exacerbate the situation with the guspnp5 driver. Sound was just unintelligible with the new guspnp5 driver... I switched to vat-4.0b2 which uses the gus driver in half duplex and that was somewhat better but still pretty bad. I also kept getting sound loops but they would only last temporarily. I should not confuse the discussion by putting vat-4.0b2 in the picture but I was desperate to listen to the Berkeley Multimedia Seminar today and was trying everything. With vat-4.0b1a -- that you have modified -- I've seen good results when my multicast traffic feed is of good quality, ie., packet losses are minimal and arrival times are orderly. But when this degrades the combination of the guspnp5 driver and vat-4.0b1 deteriorates to the point of unintelligibility, lots of echos, distortion and noise. -- Denis
