I have exactly same issues. I was able to ressolve the issue however in a simple way - increase pulseaudio buffers. edit /etc/pulse/daemon.conf find and set these two from default-fragments = 8 default-fragment-size-msec = 10 to default-fragments = 24 default-fragment-size-msec = 100 This increases pa buffer size from 80msec to 2,4 sec. Now restart pulse local server by kill -9 it and sound issue was gone for me.
