Stress tests show that DSP may occasionally be late with signaling WAIT state when all pins are made use of simultaneously plus start/stop (pause) gets involved. While this isn't tied to standard audio scenarios where only System Pin (playback and capture) is involved, ensure user is not hindered when playing with more advanced scenarios. >From DSP perspective, clock acts as a resource: low clock equals less resources, high clock more resources. Relax clock selection procedure so only low -> high switch is allowed when awaiting WAIT signal times out. Once active stream count decreases, DSP will have more time internally to adjust thus low clock selection becomes possible again.

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.
