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.
Solved! Go to Solution.

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

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?

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

Here's the problem. S21 phones does not have a built in DAC for wired earphones.
You will need a Type C to 3.5mm dongle with DAC chip.
I believe those who are seeing "Device not supported" use normal dongle which doesn't has any DAC chip.
