Question: Huge audio latency ATV4 to Airplay
I have 5 to 6 seconds of audio latency when streaming audio via Airplay from the Apple TV 4 (not 4K) to a Bose SoundTouch 30 via Airplay. The latency happens when I stream music via iPhone and iTunes Music. So the issue appears to be at the switch/router level.
The softwares are updated.
ATV is connected to the internet via ethernet cable CAT7. This is the chain: internet fibre -> provider modem/wifi router -> via CAT7 to Netgear gigabit ethernet switch -> ATV
Bose SoundTouch is via WiFi streamed by the internet provider modem/router (I'm with TIM Fiber in Italy, 200MB at my door).
I didn't have that latency neither with a portable wifi modem.
What could be the issue?
