The mixer structures were filled in two places: on driver init, and when the devices are opened. The latter made the former pointless, so we remove the former. This implies that mixer dumps may now return all zeroes, which is OK, as restoring them is meaningless as well. Things were even weirder for the (generally unused) secondary sends: Some of the initialization loops were forgotten when support for Audigy was added, thus creating the technically illegal state of multiple sends being routed to the same FX accumulator (though it apparently doesn't matter when the amount is zero). The global multi-channel init used some rather bizarre values for the secondary sends, and the init on open actually forgot to re-initialize them. We now use a not really more useful, but simpler formula. The direct register init was also bogus. This doesn't really matter, as the value is overwritten when a voice comes into use, but still.

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.
