Skype may have no sound or corrupted sound for some users on openSUSE-13.1 and this blog re-iterates what has been posted elsewhere in different places.
The method I use for installing skype is per the openSUSE wiki (where at the time of writing this blog entry it had advice labeled for openSUSE-12.3 that nominally should work for openSUSE-13.1).
I had no sound from skype-4.2.0.11 on my Toshiba Satellite Z930 Ultrabook after my openSUSE-13.1 GM installation. 
After some surfing (and also reading of a user with a similar problem in the openSUSE forum on the 13.1 RC2 thread) I made note of the following on this subject:
Where I quote from the news announcement:
PulseAudio 4.0 and Skype
*By [Arun](http://arunraghavan.net/author/admin/) | Published: **August 2, 2013*
This is a public service announcement for packagers and users of Skype and PulseAudio 4.0.In PulseAudio 4.0, we added some code to allow us to deal with automatic latency adjustment more gracefully, particularly for latency requests under ~80 ms. This exposed a bug in Skype that breaks audio in interesting ways (no sound, choppy sound, playback happens faster than it should).
Weâve spoken to the Skype developers about this problem and they have been investigating the problem. In the mean time, we suggest that users and packagers work around this problem in the mean time.
If you are packaging Skype for your distribution, you need to change the Exec line in your Skype .desktop file as follows:
Exec=env PULSE_LATENCY_MSEC=60 skype %U
If you are a user, and your distribution doesnât already carry this fix (as of about a week ago, Ubuntu does, and as of ~1 hour from now, Gentoo will), you need to launch Skype from the command line as follows:
$ PULSE_LATENCY_MSEC=60 skype
If youâre not sure if youâre hit but this bug, youâre probably not.
I applied the fix noted above and Skype worked for me.
