Sound dropouts every few seconds, with several lines appearing in the syslog each time. The process mentioned
in the syslog is
/usr/bin/pulseaudio --start --log-target=syslog
.The sound hardware is Gigabyte GA-Z87N-WIFI onboard, using coax digital output.
The sound functioned flawlessly in 16.04 Beta 2, but broke after updating to release. It remains broken after doing a clean install.
