Interesting, but sounds harmless.

Ok, this is the AOA (Apple Onboard Audio) ALSA driver. No obviously
relevant changes since v3.0 upstream. Good.
Let's take this upstream. Please send:
- a summary of the problem and a quick way to reproduce it (e.g.,
does playing a CD and moving the touchpad always produce crackle?)
- information about when it started and the version number of the
oldest kernel you were able to reproduce it with
- if this was a regression, the version number of the newest kernel
you were able not to reproduce it with
- any other weird observations
- output from the alsa-info.sh script, as an attachment
to email@example.com, cc-ing firstname.lastname@example.org,
and me or this bug log so we can track the resulting discussion.
Thanks for your quick answers, and hope that helps.
