I was trying to install spotify on linux which used to work perfectly on Gnome and when I tried on KDE it was giving error box. I wrote winecfg on terminal and got following error:
fixme:jack:JACK_drvLoad error loading the jack library libjack.so.0, please install this library to use jack
After a bit of google I found the answer to be as simple as running this command on terminal:
sudo apt-get install libjack0
After this audio was working fine. Hope this helps few others.
