Thanks for taking the time to report this bug and helping to make Ubuntu
better. We appreciate the difficulties you are facing, but this appears
to be a "regular" (non-security) bug.  I have unmarked it as a security
issue since this bug does not show evidence of allowing attackers to
cross privilege boundaries nor directly cause loss of data/privacy.
Please feel free to report any other bugs you may find.

Title:
  A2DP profile not available for Broadcom BCM4-142 on Ubuntu 24.04 /
  Linux Mint 22.2

Status in bluez package in Ubuntu:
  New

Bug description:
  My Bluetooth headset (boAt Rockerz 235 Pro) only connects in HSP/HFP
  mode, A2DP profile is not available. This results in very low audio
  quality.

  The headset works fine with A2DP on my Android phone.

  This is happening on a clean install of Linux Mint 22.2 (based on
  Ubuntu 24.04). I have already installed the correct firmware
  (`brcm/BCM43142A0-0489-e055.hcd`) and dmesg confirms it loads
  correctly. The issue persists on both kernel 6.14 and the 6.8 LTS
  kernel.

  It seems to be a regression or a bug in how BlueZ/PipeWire is handling
  this specific hardware on the new Ubuntu base, as the journalctl log
  always shows an error with the Hands-Free gateway before failing.
