I use JRiver for music only, with a Id NUC and 4 separate playback locations in the house. I use JRemote on my iPhone to play music on these sources while doing different things, and in the basement, I have trouble. Often, the playback stutters before it gets going (with clicks & pops eerily similar to the start of a vinyl record), then it's riddled with cutouts/pauses, and is generally unsatisfactory. Eventually, it'll stop playing completely, and often (but not always) with a "something went wrong with playback."
This started long enough ago that I've since upgraded my phone, improved wifi performance in the house, upgraded to MC30, and this problem persists through all of it.
Wifi throughput is plenty sufficient (300-500 Mbps), I use a mesh wifi router, and the problem is unique to the basement stereo. I've made no hardware changes to the stereo. I've tried lowering the audio quality on JRemote, and toggling "Transcode Audio" to see if it would make a difference (it didn't).
I'm flummoxed.
