Converting sample rate for specific devices

[edj]

There is a device on my network that cannot play audio encoded at a sample rate of more than 48kHz - a Sonos Ray (their basic TV soundbar). Other devices are able to play music at a higher sample rate.

Is it possible to use minimstreamer to convert audio that has a sample rate higher than 48kHz for this device only?

At the moment I am using minimserver and BubbleUPnP (which I generally use to play music on the network) and converting the audio on my phone is killing the battery! The music is played from a Synology DS920+ on 7.1.1.

If it's not possible with minimstreamer, I'd be interested in other solutions - thanks.
