Try setting/adding the following to /boot/config.txt and reboot.
hdmi_force_hotplug=1 hdmi_drive=2
First forces the pi in hdmi mode even if no hdmi monitor is detected. Second forces sound through hdmi. I'd guess the PI is switching back to analogue if it thinks the TV has been disconnected, so hopefully this will stop that.
