So am trying to simplify my current setup which works with less stuff. My PC is connected to the Beam via an old SoundBlaster X-FI USB and it’s SPDIF port. Would love to get rid of said SB device so I tried two HDMI dummy plugs (the first is this one and the second is this one and I suspect it’s the same chip in both) as they list that audio will be passed through in 2.1 - so add a middleman to fool the PC graphics card (NVidia 1650) that there is a monitor connected in the HDMI port while the monitor is in the displayport connection for maximum refresh rates.
Alas, with these 2 plugs, no sound whatsoever is coming to my Sonos Beam. So before I RMA the 2nd one as I RMA’d the 1st one, am I missing a setting or something to look out for? Changed default devices, rebooted, nothing come out.
If this is not working and will never work, anyone has a suggestion? I could get a PCIe soundcard I guess, and look at displayport splitter (which does not meet the goal of removing external devices).
