Beam Ultra on PC with no (e)Arc? Is the FeinTech AX310 an option?

I want to use my Beam Ultra with my PC. The PC has an optical out (using the Sonos adaptor), but only seems to work with PCM stereo. When playing surround  from Plex I get no sound. This seems to be a Realtek problem.

I am trying to work around this while also using more of the Beam Ultra’s capabilities. The PC has an HDMI out, so I am thinking the FeinTech AX310 could help connect the PC to the Beam Ultra since it would provide eARC to the Beam Ultra. Would I be right in thinking this?

Are there other options?

Hey ​@106rallye …

This will work! I had several FeinTech products here for testing in the past including the AX340 (big brother of AX310). What you like to get managed will work with such a hdmi eARC audioextractor. 
It just depends on the soundchips and its software capabilities what audio format will be available via hdmi out. Everything including Dolby Atmos should be possible.

FeinTech doesn’t seem to want US users to do any research on their website, I’m blocked. 
 

Just for reference, though, I did find someone using this, albeit using a slightly different source, here.

      We’re you able to achieve reasonable audio sync?

        With the input devices I have tested, yes.

          The Feintech indeed works well with my PC and Beam Ultra in daily use. I still have not found the time to use it to watch a movie, but early experiences are good.
