Kudos for at least trying to address this, MS should hang their head in shame, this is not the hardest problem to solve these days. If we could do it in 1995 they should be able to do it 30 years later.
If you open pamixer and look at applications using audio it still shows up as Skype there. At least as of a few years ago.
The regular Skype was much better and also ran on Linux, but I've come to think Microsoft was only ever interested in buying the name.
