Xi6 box and audio

Is the xi6 box capable of Dolby 5.1?  I am only getting 2.0 during live programming on all channels.

Re: Xi6 box and audio

I tried expert also and it's still 2.0.   Just to confirm,. the xi6 box can send 5.1 for live programming,  correct?

only cloud recordings are locked to 2.0 audio. Are you tuning to a network HD prime time channel program?

would you describe your audio path? sound bar? receiver? is the set top box attached to the TV to HDMI1(one) and then the HDMI ARC takes the audio to the sound bar/receiver's ARC input?

Re: Xi6 box and audio

Yes that’s right and I just started an on demand movie and I was getting 5.1 audio. So the setup and connection are fine. It only appears that live tv is 2.0.

you have a comcast rental modem that provides 'hub' internet service (for your on-demand in this case). and your connection to it is fine. the problem is that the Comcast rental modem/gateway is not 'seeing' (successfully connected to) the DVR/XR2 Hub that is supposed to provide tuner services to the Xi6. since it can't use the Hub's real tuners your live TV is falling-back (backup method of connection) to streaming live TV just like a Roku device does. Please check the coax connected to your set top box(es) (DVR or XG2) and look for a 2 inch long barrel connected to the coax (in-line). It sounds like there is an extra unneeded POE filter between the DVR and gateway/modem. if you don't find a filter like that (look on the gateway, too). then can you detail how  your home wiring is connected (amplifiers/splitters)?

Re: Xi6 box and audio

I only have two devices from xfinity. The internet device is CGM4140COM and is connected via coax in a room. I have the xi6 in the living room. There are no filters, amplifiers, or splitters.

On a side note, I have a 2019 Samsung q70 and I downloaded the xfinity stream app. I get 5.1 on live programming while using the app.

Thanks again for your help.

Re: Xi6 box and audio

I believe because your system is cloud based, you aren’t going to get the audio settings that you want
