PulseAudio 100% cpu usage under KDE

[Bernard Mentink]

Hi,

Thanks for that. Actually, I want to use Gnome rather than KDE.

I am finding that with Gnome I can have sound from Chromium/Youtube  etc,
but when I call up the Gnome sound-settings tool, then pulseaudio get's
launched and used 100% cpu and crashes Gnome eventually ...

Can I re-compile some lib in Gnome that does away with pulse?

Cheers
