Now the trigger sequence is set to SND_SOC_DPCM_TRIGGER_POST for SOF. This means FE will be stopped before BE, so BE will consume invalid data and this generates huge pop noise. This sequence is introduced for HDA DAI which requires SND_SOC_DPCM_TRIGGER_POST for some reasons. Now set default trigger sequence to SND_SOC_DPCM_TRIGGER_PRE for playback with all DAI and fix sequence only for HDA DAI. Fully tested on Comet Lake for a few cycles.

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.
