S21 Ultra USB C Headphones not working

Got a new S21 Ultra a few days ago, and I am noticing some odd behaviour with my USB C headset.

The headphones seem to work fine with calls.

With media/apps - Often with the headphone plugged in, the audio comes out the phone's main speaker. Disconnecting the usb c and reconnecting it usually forces the audio to switch to the headset.

However, if I pause video/audio for more than a few seconds or switch apps the audio jumps back to the main speaker.

I do get an android notification saying "USB device not recognised" when it stops working.

My USB-C wired headphones work fine on my S21 Ultra. At first it didn't but when you pull down from the notification bar and select media it worked.

I bought so many USB-C adapters in the past 3 days to get this problem solved, one of them was a samsung usbc-headset jack adapter and still didnt work!!!! at the end i finally managed to use all my old earphones by following the instructions on this youtube video, it was super helpful and solved my problem

Similar story here, I've my type C headphones from HTC U11, as well as 3.5mm Samsung headphones (from note9) plugged through 3.5mm to type C adapter, and both will not work.
I get the notification stating that the plugged USB device is not supported.

I find this disgusting as I have to be using my Bluetooth headphones all the time.

Samsung this is not da wea!

Guys I'm having the same issue! Samsung 21 all updated, Half of my headsets 'aren't supported by this phone' even though an old set of head phones were. I have even used Samsung's own products. Is this just a ploy to get you to buy bluetooth earphones? Anyone have any fixes?

Afraid not Julia, I just xaved and got Bluetooth headphones, zero regrets though, I prefer them to wired now.

Mine only stopped working since last phone update on the s21 

They always worked fine without problem but since the last update 

When I plug-in my earpieces it's thinking it's a charger 

And using Bluetooth galaxy buds + doesn't work well for me either since they keep disconnecting every second
