No Sound using Sonos Arc - Xbox Series X (6/13/24)

I too have an Xbox Series X connected to a Samsung TV and a Sonos Beam. The set up up is Series X to Samsung TV via HDMI and TV to Sonos Beam via HDMI ARC.

I get sound fairly consistently from start up, however if I play a game for a couple of hours and then return to the dashboard I have no sound on the dashboard or on anything else I try to open within the dashboard menu. If I go back into the game I was playing I get sound within that game but nothing else. The only way to resolve this is turning off for a longer period or unplugging the HDMI from the Xbox into the TV for an instant fix. This isn’t an adequate fix though, especially for a wall mounted tv.

When I experience these issues, if I change source to normal TV, I have sound as normal with no issue. But the second I go back to the Xbox source, there is no sound. Therefore I too believe this is an issue on the Xbox side but would be helpful if this can be categorically confirmed.

Has anybody managed to get any further with the root cause of the issue/permanent workarounds?

Thanks in advance.

I also have the same setup. Xbox Series X conneted to Samsung TV via HDMI. Samsung TV connected to a Klipsch sound bar via HDMI ARC. Experiencing the same issue described by many others.

Same issue here.

I’ve got my Series X hooked up to a brand new LG C2 using the HDMI cord that came with the Series X.

I’ve got an Atmos-enabled Vizio sound bar (5.1 + two height speakers in the sound bar) hooked into the TV’s HDMI-Arc port.

I have no issues with Atmos sound when playing games on Series X. I have no issues when watching Atmos-compatible movies in streaming apps like Apple or Disney+.

But, when I play an Atmos-enabled 4K Blu-ray Disc on the Series X blu-ray app, I get this weird audio buffer after a few minutes. The movie may go 20 minutes without, but once is starts going it gets more consistent. This issue persists regardless of which Atmost-enabled 4K Blu-ray I use.

I’ve tried messing with the settings - switching back and forth on allowing pass through, etc.

Funny thing is, on my older TV (a TCL Series 6 which was not VRR or 120 hz compatible) I had zero issues. My Series X would play Atmos 4K blu-rays no problem. Only difference I can think of is that on my old setup I hooked the Series X directly into the input of the sound bar and then output from the sound bar into the TV (it was the only way I could get Atmos to work on the old TCL Series 6). On my current set up with the LG C2 I don’t do that because passing the Series X through the sound bar would take away the VRR and 120 hz capabilities my new TV can do.

Can anyone help?

I have not waited 24 hours yet, but I have waited 13 hours or so which is significantly more than usual. And yes I am on Xbox Series X/S console. I have restarted multiple times.

Don't know abaout Panasonic but there is problem with Lg and X's Arc sound. There is no sound at all. So just wait for update/fix
