We now enable ints even before triggering, and disable them only after stopping - otherwise there is a race condition we may plausibly run into when we pause/resume near the end of the buffer. Updating the epcm->running flag is moved the same way, as it affects the *_pointer() functions, which are called by the interrupt handler. Also, factor these out to own functions, for clarity. For multi-channel, the extra voice is now triggered after all regular voices - we wouldn't want to receive an int before all channels have passed the period boundary.

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.
