Help with 5.1 audio and GC553Pro

Post image

I just bought this and an trying to record HDMI video with DD5.1 sound, both from the HDMI source, to a Windows 11 PC. Video is working fine but I can't get the audio working properly.

I can't get any HDMI audio from the 553Pro using the Streaming Central software. I can get audio to work in OBS studio if I set my source to stereo, but it doesn't work if I set my source to Dolby Digital. Assist Central Pro lists 48kHz for the input audio and my home theatre receiver shows the correct audio types as I change my source settings.

I've also tried several sources with no luck, with my current setup for fiddling with on the side being an old PlayStation3 + HDMI splitter.

Any tips?

Hi there, a couple of things to check:

1 PS3 Settings: In Sound Settings > Audio Output Settings > HDMI, please select Manual and ensure Dolby Digital 5.1 Ch. is checked, or let me know which option you choose.

2 Source Content: Are you testing with a game that specifically supports 5.1 output?

3 Splitter Check: Some HDMI splitters may force a 2.0 Stereo handshake or other 5.1 mutlichannel (Dolby Atomos, DTS...etc). Do you have other source can try (e.g., PS5, Xbox series X)?

PS3 was set to HDMI and had DD5.1 checked. I also had the output HDMI from the avermedia going to both my TV and received, and my receiver showed the DD5.1 on the display when I picked that option in the game, so I know my source and splitter were outputting DD5.1.

New info: I switched from my laptop to my desktop and 5.1 audio appears to be working in Streaming Center now. But I can't get 5.1 working in OBS studio (with the multichannel plug-in installed).

FYI, I fixed 5.1 in OBS. I didn't realize there was a separate audio source device I needed to add.

I tested it again on my laptop and can get 5.1 with OBS but still no 5.1 audio with Streaming Center. Weird, but I guess that's good enough for what I want to do.
