This issue is not related to FLAC streaming only. I stream WAV and I
also experienced the issue with 7.3.3. For now I went back to 7.2.1. and
that works fine. I guess it is fair to say that the issue is more likely
to occur when streaming larger audio formats (lossless). 

I noticed that the streaming generates a relatively constant data flow
on the network. Near the end of a song, the dataflow becomes more
important. On a 10Mb network, the load went up to 30% which is
significant. This was measured with only one SB3 streaming audio. On a
100Mb this will drop down of course. But nevertheless, streaming
generates an important amount of data packets on the network. It is
therefore very much possible that some people may run into issues if
they already have a busy network. In a cabled environment this is very
easy to solve by upgrading to a gigabit backbone. Gigabit networks can
even use jumbo frames if required and that will benefit the network
traffic even further. But wireless is a different story. Since an Access
Point is a bridge, it will bridge all cabled traffic to the wireless
(and vice versa) putting a lot of load on the wireless network if the
cabled network is busy. 

It might be wise to try and find ways to decrease the traffic generated
by the streaming protocol. One way of doing that is to use a larger
buffer in the players. A larger buffer would give the player more
“stream ahead” room and this would decrease the possibility of running
out of buffer. But I don’t know if that is possible in the current line
of players (hardware wise). 

In any case, there is a difference between the streaming of SC 7.3.3.
and SC 7.2.1. By knowing this, it should be fairly easy to compare the
traffic generated between those two versions and find a solution to the
issue. In order to debug an issue like this, you’ll need to use a
network sniffer. Microsoft provides one for free here:
