HDMI Capture Card that can successfully record Dolby Digital audio?


Just like the title says, is there an HDMI card on the market right now (or even discontinued) that at the very least can record in 1080p, 30fps, and accept the raw feed of Dolby Digital audio? I’m at my wit’s end here.

First I was using an Inogeni 4K2USB3 card, but that apparently was upsampling the audio feed, and therefore rendering it unusable.

Then I went back to my old AVerMedia Extremecap U3 from back in the day, but that was only a patchwork fix and not a permanent solution as eventually the drivers’ HDCP detector went haywire and all I get now is a black screen, no matter what I try to record with that.

So I said, okay. This time, I’m going to take a chance on the Elgato HD60 S unit, since it allows for 3rd-party support on recording software, you’re not obliged to use their 1st-party application and hardware encode what you’re recording. Then I learn, after the fact, of course, that it doesn’t record Dolby Digital audio at all. You try and all you get is silence as opposed to the white noise you’d normally get. Why they enabled a capture device to so specifically inconvenience their paying customers, I’ll never understand.

So, I come to you with a simple question. Are there any capture cards that are not Inogeni, AVerMedia, or Elgato that can simply record in 1080p with DD audio at the helm? I’ve seen those non-brand name ones on Amazon, but I hear you run a risk of the signal just being really bad SD disguised as HD.

Thank you kindly.


I have looked for many years for exactly what you describe. I have talked with many manufacturers, even purchased products after being promised they would work, only to find out they don’t support it after all.

Basically, there are none.

The only way to get the audio is to use an spdif stripper and a separate recording device that can losslessly capture the compressed audio bitstream. And even that is stupidly difficult.
