My AMD Kaveri A8-7650k system 8gig+SSD has never had sound unless (1) install pavucontrol and then (2) run the pulse-install script.
However now with 17.0 in the last 3 days, after successfully installing pavucontrol and rebooting, after then running the pulse-install script, the system will never boot again. Have verified this several times on a fresh 17.0 install that only then has pavucontrol then pulse-install done to it.
17.0.1 will not even install at all, the system hangs up during boot for 37 seconds at the MHWD stage and then a blinking underscore and no boot.
Also if run pamac-updater on the 17.0 install now, the system will never boot again.
So am limited to installing 17.0, and never updating, and never running pulse-install script-thus no sound. Within these limits everything works ok, including opera/google-chrome-stable/libreoffice/dash/evince/libgsf/imagewriter/font-manager.
Also in general many of my 17.0 clients' updates are not happening in the last 3 or 4 days.
