Probably should have submitted a new post, but here goes.
Just wanted to add my two cents to this forum, and sort of introduce myself. Am relatively new to the world of Raspberrypi audio, Last month I paid way too much for a used device made by Pro-Ject. went through a few different flashes then discovered Rune. The audio quality led me to pay way too much for a pi4b 4g which I am running Rune audio on currently.
Then last week my router took a dump, had to reflash it, then my phone upgraded to android 12, since then the Remote wouldn't work.
I found for it to work I followed avahi settings, then rebooted, app still didn't work so I then went into phone app settings and deleted cache and data, now it works quickly and smoothly.
