            Bug ID: 219003
           Summary: "Bluetooth: hci0: corrupted SCO packet" on W800BT on
                    kernel 6.9.7
           Product: Drivers
           Version: 2.5
          Hardware: All
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P3
         Component: Bluetooth
          Assignee: linux-bluetooth@vger.kernel.org
          Reporter: brauliobo@gmail.com
        Regression: No

On kernel 6.9.7, I get several errors "Bluetooth: hci0: corrupted SCO packet"
on dmesg while playing audio.

On the user side, the Edifier W800BT audio is interrupted by several seconds
and gets back by itself. It happens at least once every minute.

Reverting to 6.6.36 LTS solves the issue.

The dongle used is Baseus BA04 Bluetooth 5.1 Usb.

Below is the messages on linux 6.6.36:

--- Comment #1 from The Linux kernel's regression tracker (Thorsten Leemhuis) (regressions@leemhuis.info) ---
A few notes from a bystander:

* please attached a dmesg from a kernel where this problem occurs, ideally with
the latest 6.10-rc version or newer

* no developer might look into this, unless you bisect which change causes the
problem, as then someone is obliged to fix it
(https://docs.kernel.org/admin-guide/verify-bugs-and-bisect-regressions.html )

* not sure, the bluetooth developers might not even see this report (search for
bugzilla on
https://linux-regtracking.leemhuis.info/post/frequent-reasons-why-linux-kernel-bug-reports-are-ignored/
for details)

I can't reproduce it anymore, so I'll close it for now
