Hello - I have gone through process of testing mic and sound - all work on my new Lenovo but whenever I try to make or receive call via Skype, it says "Problem with playback device". On the other end, it tells the caller I need to update to new version of Skype. I recently did this - I am running Skype 5.5.
I'm not sure what operating system you are using, but I have an Windows XP version of the fix. If you are running Vista or Windows 7 the procedure should basically be the same. Here is the link for the instructions:
Skype Enterprise Support
I fixed it by going to that website the previous user put (https://support.skype.com/en/faq/FA11067/how-do-i-
I have windows 7, though.
So, I went to control panel/hardware and sound/Sound/Manage audio devices
I clicked the speakers I was using, then hit the properties button
disabled the speaker, then went properties again to enable it back on
then clicked on the speakers, again, hit configure
then click test.
go through that process and voila.
All good in the hood.
