It certainly sounds like trashed packets are not being retransmitted, and 
if the dongle does Bluetooth 2.0 I start wondering about the Volis audio 
gateway.  But my Russian isn't good enough to find the Bluetooth version 
that it supports.

When I play music to headphones and Bluetooth 2.0 is used on both ends, I 
have no trouble with interference from WiFi.  However, this is on a laptop 
machine with an internal Bluetooth transceiver that coordinates with WiFi 
so only one transmits at a time and they avoid transmitting when the other 
service expects a scheduled packet.  (Dell Inspiron 6400 with Dell type 355 
internal Bluetooth and Intel IWL3945abg WiFi.)
