Can the cable provided with the Sonos Beam be used as a regular HDMI cable? Somehow in my mind I wonder if the provided cable only works for ARC audio since the cable diameter is smaller than any of the other HDMI cables I've recently purchased (HDMI2). I also am mystified why there seems to be no way of distinguishing the various classes of HDMI cable (ARC, Ethernet, HDMI2, etc.) and data transfer speed capability. I've never seen any markings on any of the HDMI cables so how do I know if I have HDMI or HDMI2 or etc. Is seeing that it doesn't work the only method? And I am not sure what would manifest itself as not working. Drop outs/no data connectivity/etc.?
