HDMI capture card that'll do 8ch LPCM?

[lowerfe]

I have an HTPC that acts as my video and audio source, and I run a PC DSP on this (EqualizerAPO), then output this to 5 active speakers with a Motu Ultralite MK4.

I'd like to add a PS5 to this setup. I'd like to use my PC to process the audio. Is there an HDMI capture card that will pass 8 channel LPCM to my computer? This way the audio from the PS5 will play on my computer, which then plays through my speakers.

Thanks
