Audio Output Mode / Use Custom Audio Device Input

[shiftlocked]

Hi Everyone,
On a MacBook Air M1
Big Sur 11.6

I'm trying to capture audio from my cheapo USB Capture card. On the instructions it says when adding a video device, scroll down to the input settings, audio output mode and select output desktop audio (wave out) and select use custom audio device.

This feature appears to be missing on the Mac? Without it the sound is choppy and unusable.

Anyone aware of this feature missing or a potential build with the feature available

well "elgato" is a crappy company and they are liars when it comes to after-sale support so you will have to salvage out a solution for your crappy video capture device.
You will still have to set audio mode to " output desktop audio (wave out) " (because if not, obs will produce warning about elgato's crappy sound solution that reach max audio buffering) and you wont use audio from elgato device but your display/monitor instead..

You will use a 3.5mm stereo cable from your monitor/tv's headphone jack into your pc's line-in jack (may have to use a "ground loop isolator" (5-10$) to eliminate some weird interference noise. and will have to adjust (syncronise)audio delay of the line-in (monitor's incoming sound) to match the elgato's video feed. never will have to use elgato's crappy sound interface again.
