If you are using the latest Linus tree, it'd be better to pull the
above GIT tree onto it. If you are using the older kernels, an easy
way to try the latest ALSA code is to build from the snapshot
tarball. There are daily tarballs and the latest snapshot tarball.
All can be built just like normal alsa-driver release packages, that
is, installed via the usual spells: configure, make and make
install(-modules). See INSTALL in the package. The snapshot tarballs

Say Y here to enable RTC timer support for ALSA. ALSA uses
the RTC timer as a precise timing source and maps the RTC
timer to ALSA's timer interface. The ALSA sequencer code also
can use this timing source.
To compile this driver as a module, choose M here: the module
will be called snd-rtctimer.
