I've seen the same thing, and it appears to be from attempting a
native bridge.  You can try the attached patch to disable native
bridging.  It cut out the annoying silence completely for me.  This
may be a bad thing (unnecessary CPU utilization due to same-codec
translation), but I have not experienced any problems.
