Thank you for your reply. No, I want to connect speakers to my PC sound card and be able to switch to PS5 sound. To do this I was thinking of using the HDMI Audio Extractor and the 2 port 3.5mm Jack switching box. Connect the speakers to the switching box and one output to the PC sound card and another to the extractor.

Do you mean at the same time?
You need an HDMI switch for that.
