Fix HDMI audio for ubuntu/NUC

My NUC is hooked to Philips 221E via HDMI cable. The audio is fine if the monitor is never turned off. Once the monitor reboots, the distorted audio really make it unusable.

To solve the problem at ubuntu, append 'tsched=0' to 'load-module module-udev-detect' at /etc/pulse/default.pa
