I use OBS (21.1.0 64 Bit) for Streaming and Capturing but the AV_io 4K will not send sound from any source attached to it.
The Video Signal is very good and the low Latency is remarkable, but there is no Sound at all and the Sound Meters in OBS don’t even flicker.
I’ve tried it with a PS4 Pro, a PS3, a PC but nothing to hear.
The Device shows up in Recording Devices, but the Meter next to it won’t move.
I’ve tested it with different HDMI-Cabels, not longe than 2 Meters, connected the Source directly and through an HDMI-Splitter.
Before i decided to wrote down my Problem, i fumbled around today and discovered some strange behaviour:
I deleted the connected Av_io from the Device Manager, restarted and reconnected it -> Windows installed the Drivers and suddenly there was Sound!
But not that Sound that i was looking for. It stuttered, it where distorted and was getting quieter and quieter and then disappeared completely.
At this Point, i am really helpless and had no idea, what is going on.
I would be very grateful for any Idea or Hint that helps me solving this weird Problem.
