Windows 11 Bluetooth no sound/microphone and crashing

My Letsfit T13 earbuds act as you described. But on Win 11 upgraded from 10 laptop, of I start Zoom before starting ang other software including the chrome browser and it is running in the background, they work as they did on Win.10. Using say YouTube or YouTube TV and other programs with sound all is well

If I stop Zoom running in the background, it reverts to the sound output issues. No others responding have apparently tried this, so don't know if I just stumbled on this and why it works with Zoom running in the background.

Windows 11 still not fixed!!

Aukey EP-T21 headset earbuds work fine with iPad, android phone, and Windows 10 laptop. They pair and connect (albeit intermittently) but no sound or microphone with Windows 11 desktop (brand new) or laptop ("upgraded" from W10 last year). Sony WH-CH700N headphones pair and connect fine with all devices, including both W11 machines. All troubleshooters report no problems. All drivers updated. "Zoom first" fix works for a few minutes on W11 laptop then fails, plus sound is terrible.

I agree with WalterHildebrand, this is simply unacceptable behavior from MS. Fix the problem and stop telling us to try fixes that will never work!!

Windows 11 stlill not fixed.

The strange thing is that if I start ZOOM before I start my Chrome or MSN browser, that the earbuds do work.

They work for all apps that I use the earbds for.

They continue to work as long as ZOOM is running in the background.

BUT, if I stop ZOOM running in the background then the problem of the earbuds not producing sound recurs.

I finally managed to solve this issue.

I purchased a new SSD and installed Windows 10. I am finally able to use Airpods pro and Sony WH-XB900N freely.

I have the same issue:

1.) Earbuds connect and work on Mac, Android, Windows 10

2.) Earbuds connect but don't work on Windows 11 (tried on multiple machines)

It is very obvious that Windows 11 has serious issues with class compliant bluetooth earbuds & headphones working properly. It seems that Win 11 is not capable of recognizing the correct audio sample rate (it is setting them at 48kHz instead of 44.1Khz). Once it even set it at 12khz (audio cassette quality). There is no way to set it manually. First you incapacitate us, dont allow us to fix things manually, at the same time you fail to fix your flawed auto-recognizing feature. If you can't handle new features, don't introduce them.

Instead of posting standard copy and paste bluettooh troubleshooting answers that don't work, it would be time Microsoft acknowledges that the problem lies in their OS and finally directs one of their 163,000 employess to look into and fix this major connectivity restraint.

That Windows 11 cannot even properly connect to class compliant hardward is pathetic. You should have never released this banana OS.

Please MS, stop wasting everybody's time!

JUST FIX THE PROBLEM!

PS: I worked with every OS Microsoft has every written. The only one that ever worked without a flaw was MS DOS on the Apple IIc. Everything else that came afterwards was always headache, headache and headache. I must have spend two years of my time in man-hours just fixing issues on Microsoft's operating systems. MS is stealing our valuable time and no one is compensating us for it!
