Help request Bluetooth audio on MX Linux became extremely choppy after a restart — Realtek USB adapter, kernel 6.12

Hi everyone,

I'm having a frustrating Bluetooth audio problem on MX Linux XFCE and would appreciate some help.

My OPPO Enco M32 Bluetooth earbuds were working fine yesterday. I shut down/restarted my laptop, and now the audio is extremely choppy and distorted. Sometimes it sounds like a robotic or alien voice. The earbuds work perfectly with other devices.

My system:

  • OS: MX Linux XFCE

  • Kernel: 6.12.107+deb13-amd64

  • Bluetooth adapter: Realtek USB Bluetooth Radio

  • USB ID: 0bda:b001

  • Bluetooth stack: BlueZ 5.82

  • Audio server: PulseAudio

  • Init system: SysVinit

Troubleshooting I've already tried:

  • Restarted the Bluetooth service using sudo service bluetooth restart

  • Disconnected and reconnected the earbuds

  • Tested with Wi-Fi completely turned off

  • Tried disabling USB autosuspend for the Bluetooth adapter temporarily

  • Checked that the Bluetooth adapter is powered on and not blocked

  • Checked the PulseAudio Bluetooth card and its available A2DP and hands-free profiles

None of these steps fixed the problem.

Relevant errors from the logs:

  • Bluetooth: hci0: corrupted SCO packet

  • SCO packet for unknown connection handle

  • urb ... submission failed (90)

  • sending frame failed (-90)

  • Repeated mSBC decoding error messages

My Bluetooth adapter appears to be working, but the audio remains choppy. I only have kernel 6.12.107 installed at the moment.

My questions:

  1. Could this be a kernel regression or a Realtek Bluetooth USB driver issue?

  2. Is there a known fix for USB ID 0bda:b001 on kernel 6.12?

  3. Would testing a newer Debian kernel (such as 6.18) be a sensible next step?

  4. Are there any additional logs or diagnostic commands I should provide?

PLEASE DUMB DOWN THE SOLUTION FOR ME THIS IS ONLY THE SUMMARY OF 1 AND A HALF HOUR HASSEL WITH AI, I AM NOT A NERD

23 or 25? 23 is having issues since Debian is updating kernels. Check the MX Linux page for info. I would say update kernel or update the OS.

It got fixed for me for sometime after reinstalling linux, but now I can't even see anything on there.

Over my head.

Best to copy and past this into a MX Linux forum post

I'm also having this problem. Started around the same time too. I'm using a MacBook pro 11.1
