Got this problem on gentoo, very annoying for skype tagged each and every of its notifications as a "phone". Below is a workaround:
Hello, last night I installed fedora 12 , and as I expected I had the rhythmbox + skype problem , every time something was making sound on skype , the rhythmbox was muted and paused.
On the file:
as root I commented that line :
load-module module-cork-music-on-phone —>
# load-module module-cork-music-on-phone
and I killed ( killall pulseaudio )
When it started again , everything were working fine ! Hope it helps other people. Special thanks to the advice of Bl…F…
