Hello,
My Arc will be delivered tomorrow. I have a question about connectivity in conjunction with the 4k Firestick.
In order for the 4k feature to work the Amazon Firestick must be connected to an Arc/eArc HDMI port. I’ve confirmed this is the case, no 4k on any of the other 4 HDMI ports on my TV (Vizio M75-C1) using the 4k Firestick. My TV has only 1 arc/earc HDMI port.
The SONOS Arc also requires the arc/eArc HDMI port for full functionality. What do I lose if I use the optical-out option? Are there any other connection options.

Using optical, you would lose any CEC functionality, and be restricted to Dolby Digital 5.1 as the maximum codec. So no Atmos.
