System (bought from 2021)

• Arc
• Five (left)
• Five (right)
• Sub Gen 3
• Sony 65x9500H 4K HDR
• MacBook Pro 2019 Cantina 10.15.7

Set up

• Arc connected to TV via HDMI 3 ARC / eARC
• Macbook connected to TV via USBC to HDMI
• All devices are connected to 1 wifi
• I watch movies streamed off my laptop onto the TV. There are two ways for me to get audio from the Laptop to the Sonos 5.1 system:

1. I change the laptop audio output to Sony TV. The TV then pushes sound to the Arc & Sub; I do not get any sound out of the Fives. When I press buttons on the Five, I can control the whole system like pausing and turning up the sound but I cannot get any sound from them
2. I change the laptop audio setting to the Sonos 5.1 airplay setting. However, the connection lasts for about 20 minutes before it starts breaking apart or disconnects completely. I then have to toggle the sound from laptop speakers to Sonos 5.1 airplay OR I wait: if I wait, sometimes the sound comes back, some times it does not.
   
   I do use a VPN (as I live in Shanghai so there’s no way around not using one).

Could someone help me with the problems of 1) 2)?

Thanks! (Below is what I went through with the Sonos robot)
