A2DP sink couldn't be detected

If you are filing this issue with a regular release please try master as it might already be fixed. Also test with PulseAudio because if it doesn't work there it's not going to here either.

Description of Problem:

I own a Sennheiser cx400bt earbuds. It's working fine on other devices. It was working fine on this PC as well, but now it seems that A2DP sink couldn't be detected. Screenshot_from_2021-07-02_17-38-38 I believe the issue started occurring after a recent system update. I tried downgrading the pipewire and bluez, but it doesn't work. Reinstalling the pipewire and bluez also didn't solve the issue.

To investigate the issue, I also tried with another PC with the same OS and same version of the kernel, pipewire, bluez, etc. It works. Screenshot_from_2021-07-02_17-48-56 Did I misconfigure something that leads to this issue? Please advise.

How Reproducible: Always. I had tried pairing the earbuds and reboot the PC many times.

Steps to Reproduce: Since this issue only occurs on one of my devices so far, it might not be reproducible. I don't know what is the cause.

  1. Connect to the earbuds via Bluetooth.
  2. Check the sound setting, the A2DP sink isn't available.

Actual Results: Refer to the first picture.

Expected Results: Refer to the second picture.

Additional Info Eg. Additional Kernel Patches, pw-dump -N > file (As Attachment Please):

 ❯ pw-dump -N > file

Seems doesn't work. I can provide logs if you tell me how to get it. Thanks!
