Mixing jumbo frame enabled devices with non jumbo frame enabled devices is a recipe for certain disaster. Things will appear to work, until they don’t!
Most Android boxes and things like Raspberry Pi do not support Jumbo frames. Some android boxes will refuse to work (or freeze intermittently) if they are on Jumbo frames.
Careful consideration has to be made to make sure everything works as designed. Placing your NAS and music streamer on the same switch not only provides the best efficiency, it is also going to reduce headaches!
As with everything, start start simple and expand from there. The first step is to create a simple network between your NAS and Music Streamer. If you do not perceive any audio benefits after a few days, then there is very little point to proceed to the next steps. Quit while you’re ahead.
