Minim stream being throttled on QNAP NAS ?

[simoncn]

I tried playing a 256 kbps MP3 album from my QNAP NAS. The network usage you have posted looks different from what I am seeing (see attached image). My graph shows regular peaks at the start of each track, then very little traffic thereafter.

How is your QNAP connected to the SONOS over your network? Can you try changing this? For example, if this is a wired connection, can you try wireless instead (or vice versa)? I think the issue is probably with your network connection rather than something on the QNAP.
