Reddit mentions of USB Sound Adapter, EC Technology Aluminum External USB Sound Card Audio Adapter with 3.5mm Stereo Headphone/Speaker and Mono Microphone Jacks for Window XP/Vista/7/8, Mac OS 8.6 or Above- Silver

>that an analog to USB adaptor will not work for the training or be accepted.

This isn't a thing, and if it existed it would not work. USB is a digital only output. If a headset is USB, that actually means it has a little DAC (digital to analog converter) in the cable of the headset.

I cannot think of a reason why they would require you to use a USB headset. It seems ridiculous, unless the computer just simply do not have onboard audio.

However, you could get a cheap USB to analog adapter and use that with your current analog headset. Most of this sub is concerned with more "audiophile" DACs and headphone amps, however something like this should work

you need an external sound card like this:

be sure to get a usb extension wire as the PS4 is just an awful shape that doesn't fit usb's that have a large base like most sound cards

OR

a DAC with an optical cable like this:

a suggestion for a mic if you need a great one that's cheap:

you can also use any mic that plugs into a usb slot like a blue snowball or other desktop mic. I'm not sure what exactly your setup is so I can't really tell you whats best but hopefully this helps.

You could try a USB sound adapter. The sound will be produced on the USB itself so that would rule out a problem with the headphone jack on the laptop.

Right now, I'm using a cheap USB headphone like this: https://smile.amazon.com/gp/product/B014F2VUO8. As long as it's plug and play, I think it will be fine on a Raspberry Pi. I looked at the specs for Centrance and it says it's plug and play with Windows, Mac, and Linux. So, you should be fine. I would verify if anyone owns one and has had any issues. If someone has, then it should be fine on a pi.

I've been meaning to try the Zoom R8's audio interface since that is what I use to record or the Novation X-Station's audio interface. Worth a shot. I wouldn't record with the cheap headphone usb audio interface I have now. I've been using it while I learn the ropes of pure data and what I can get away with on the Pi.

I understand in order to use a mic you need this....

However, I just wanted to confirm that the PS4 pro will recognize both USB ports actively. One USB port will have the xim4 plugged in supporting the keyboard and mouse, and the other USB port will have the above adapter plugged into it supporting the headset and mic. Both USB ports are being used for the one game we are playing by one person with one controller. Is this correct? Thank you in advance.

I bought an ancient headset with the green and pink adapters for 6.00 and a USB adapter off Amazon for 4.00.

This is what I bought locally on sale. You can buy the 3.5mm adapters that plug straight into your controller also and use an older headset that way.

Well, technically, the easiest way would be to buy a USB sound card. Probably not the cheapest though. They do make some pretty nice ones though.

Edit: Perhaps not as expensive as I thought might not be great quality though.
