commit 6a83d6f3bb3c329a73e3483651fb77b78bac1878 upstream. When a Opencomm2 Headset is connected to a Bluetooth USB dongle, the audio playback functions properly, but the microphone does not work. In the dmesg logs, there are messages indicating that the init_pitch function fails when the capture process begins. The microphone only functions when the ep pitch control is not set. Toggling the pitch control off bypasses the init_piatch function and allows the microphone to work.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
