Hi there,

I’m struggling to get my Sonos Beam set up to play audio from my PC and was hoping someone might have seen my issue/have some troubleshooting tips!

I’ve been following this nice guide to get my Beam working with my Windows 10 PC. I bought the suggested DAC and installed the associated drivers. It all seems in order - there’s now a CMedia audio wizard in my System Tray, and when I plug in headphones to the `Front Out` port in the DAC I can hear audio from the PC. So far, so good!

Unfortunately I’m falling at the next hurdle - getting the audio through to be played out by the Beam. Using the CMedia wizard I can toggle the SPDIF out option (it’s obvious when this is on because you can see the red light coming out of the SPDIF out port on the DAC). I then attached the HDMI cable and HDMI-to-SPDIF adapter that came with the Beam. Having done this though, no audio seems to come out of the Beam!

I thought perhaps I’d need to go through the setup procedure in the Sonos App to get the Beam to recognise the input. However, when I do this the app tells me that it can’t find any HDMI-ARC input. I was expecting that the SPDIF adapter should convert into HDMI-ARC - perhaps there’s some “I’m here” signal that it’s not properly sending? Either way the app doesn’t seem to help me make any progress here .

So I’m at something of a loss! Ideally I’d try a different speaker and see if it’s a problem with the Beam or some other part of the setup, but I don’t have anything that takes SPDIF for me to test with. Is there some crucial step along the way that I’ve missed?

Any help would be greatly appreciated!
