Comment # 14 on bug 972238 from Takashi Iwai

Please don't paste such too long text to Bugzilla form.  In such a case, use
attachment.

Also, please give the all requested information.  Give alsa-info.sh output at
the muted state before starting playback.  And, tell which desktop you're
using.

You seem to be mixing up the many repos, and this is out of support.  Try to
exclude the non-standard repos (e.g. multimedia:*) to see whether you can still
reproduce the issues only with the official Leap packages.
