The voice volume is a raw fractional multiplier that can't actually represent 1.0. To still enable real pass-through, we now set the volume to 0.5 (which results in no loss of precision, as the FX bus provides fractional values) and scale up the samples in DSP code. To maintain backwards compatibility with existing configuration files, we rescale the values in the mixer controls. The range is extended upwards from 0xffff to 0x1fffd, which actually introduces the possibility of specifying an amplification. There is still a minor incompatibility with user space, namely if someone loaded custom DSP code. They'll just get half the volume, so this doesn't seem like a big deal.

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.
