I'm running all sources - xbox one x, ps5, PC, xiaomi 4k box, into a Sennheiser Ambeo soundbar, then the soundbar output into the capture card/switcher, which has other inputs at this point, a nintendo and a ps3, then onto the projector (used this way on previous card, no issue). It must be being caused by signal loss in the switcher to the USB output when there is a signal change. I'm told there is a code work around Paulchen-Panther do you know of anything?
amend: on old capture card I could even unplug the USB and when put back lights still on
amend 2: its the Sennheiser that signal drops out on (I think), although again was not an issue on old card
