I recently bought my Sonos Beam and hooked in up with my 10 year old plazma Panasonic Viera TX-P50S20 E through its HDMI ARC slot. To other HDMIs on my TV I plugged my cable box outputing Dolby Digital and Google Chromecast device. The problem is no matter which one I use I’m not getting DD, only PCM. I also tried the optical output from my TV - same thing. I googled on this issue a bit to find out I’m not the only one and even in Sonos community I found folks reporting the same problem.
The BIG question is: has anyone been able to fix / workaround this or the situation is hopeless and there’s no way this could work as Panasonic does not passthrough DD ?
Anyone?
