Hi there, there is a known issue with all variants of the Raspberry Pi 3 where Bluetooth and WiFi interfere with each other. This will only impact the performance of balenaSound if you use a Pi 3 as the master server to do multi-room bluetooth streaming, resulting in stuttering audio (Airplay and Spotify Connect will work fine, as well as all streaming methods with multi-room disabled). In this cases we recommend the use of a Raspberry Pi 4 as the master server or a Pi 3 with an external bluetooth dongle.
