Speaker output goes to SPDIF instead of HDMI

Did anyone find a solution to this issue?

No. Someone from Sonos support help!

Sonos Support doesn’t live in these forums, only Sonos Forum moderators, of which there are very few. 

I would recommend that you make sure your Sonos is up to date with both software (controller) and firmware (speakers), and then  submit a system diagnostic within 10 minutes of experiencing this problem, and call Sonos Support to discuss it.

There may be information included in the diagnostic that will help Sonos pinpoint the issue and help you find a solution.

When you speak directly to the Support staff, they have tools at their disposal that will allow them to give you advice specific to your network and Sonos system.

Thanks. Sounds like a good plan. :)

May be slightly painful, in terms of waiting, but they’re much more likely to have an answer than this community is ;)

I called Sonos tech support when this issue came up. The guy seemed unaware that others were experiencing this problem. He ha me do a number of things to try to fix the problem—hard reset, swap HDMI cable— but none worked. His solution? Send me a new Sonos HDMI cable. Just arrived this morning. I’m skeptical, to say the least. I’ll update this post after I’ve had a chance to make the switch.

Hey at least you got a new HDMI cable!

Don’t overlook the silly. In a few cases the HDMI cable was not making full contact in its socket. Sometimes a little extra push is necessary.

I have the same issue! No red light from the optical cable coming out of the back of my Playbar. Was gone out of the house for a week and came back and had this issue. Any progress or fixes? Also seeing the SPDIF input instead of HDMI

I’m concerned about your post…the red light comes out of the TV, and is transmitted to the PLAYBAR. There is no red light emitted by the Sonos. 

Because you’re using SPDIF, with a PLAYBAR, that’s what you should be seeing. Unless you don’t have a PLAYBAR, but instead a Sonos soundbar that uses ARC.
