One UI 6 Update & Bluetooth Headset No Audio

[alexm958]

After updating to One UI 6 today (S23 Ultra), my Bang & Olufsen headphones no longer play audio. They connect fine, but no audio plays. Any idea? The firmware is up to date on the headphones.

My Galaxy Buds Pro are working fine (to be expected with a Samsung=Samsung product)

I've been having issues with my Audio Technica ATH-TWX9. Since the last Samsung update, I can set up the earbuds but after that, it's a problem page, they will play audio, but I just can't access the EQ or any other functions of the app itself. I've rebooted and factory reset twice to no avail. So I pulled out my Zflip 3 which has been in a box for months without the current update and the earbuds work just fine. I don't know what to do now to fix the problem, I sent the earbuds to Audio Technica and they sent the earbuds back stating no issue was found after testing on different cellphone devices. I don't know what to do now.

Same here with A53. Conneted but no sound from car system (vw).

Have been having a similar problem when making / receiving phone calls in my car.  The car's radio gets muted for the duration of the call, but the call itself doesn't get transferred to the car's stereo and still comes out of the phone's own speaker.

Have just (midnight on Christmas Eve) had another One UI 6 update arrive at the phone, so fingers crossed that this update will fix all this. 🤞

Same issue here after OneUI 6 and Android 14 update on Samsung Galaxy S21FE : bluetooth audio doesn't work anymore ! 😠

I have a tab 6 lite, purchased Bose QC headphones, 2 different pairs, audio stops working on both, even though they still seem to be connected. This happens when switching from my S21, back to tablet. I have recently gotten One Ui 6. So annoying. Anyone have any thoughts?
