Just a thought, a couple of days ago I was getting momentary dropouts as you describe, when I was syncing my study player (see sig) and a Boom, whilst using a Pi4-4GB as LMS server. I have never had this problem before when using any other flavour of RPi. I am now back using a Pi3B+ for server and the 2 players sync without dropouts. Try using a Pi3/LMS with your Mesh, see if you still get glitches? The Pi4 is now in my spare Pi box, it was getting up to 80°C. *Server - LMS 7.9.2 *Pi4B/pCP 6.0.0 18K library, playlists & LMS cache on SSD (ntfs) *Study -* Pi3B+/pCP 5.0.0/pi screen/HiFiBerry DAC+/jivelite, *Lounge* - Pi2/pCP 5.0.0 > HiFiBerry DIGI+ > AudioEngine DAC1 > AVI DM5 *Dining Room* - Squeezebox Boom *Garage* - Pi3B/Pi screen/HiFiBerry DAC+/pCP 5.0.0 > Edifier R980T *Spares* - 2xTouch, 1xSB3, 1xRadio, 6xRPi ------------------------------------------------------------------------ kidstypike's Profile: http://forums.slimdevices.com/member.php?userid=10436 View this thread: http://forums.slimdevices.com/showthread.php?t=110765
