Support SONOS BEAM (and ARC sound system) support. TV might need to be disconnected from wall plug for a few minutes if Arcana is updated in system. This mode is still in Beta.
Selection for Multi Ch PCM support or not (older/earlier SONOS Arc CDS and newest/latest SONOS Arc CDS). Source must be restarted after any changes.
Added DTS/DTS:X support (off by default). Source must be restarted after any changes. Note that this mode is only compatible with eARC sound system that support DTS/DTS:X (not the case for SONOS Arc currently)..
