More pulseaudio issues with HDMI

[Pace]

Hey everyone,

So I know I have an issue with Pulseaudio. Every-time my system is left alone for a while, the HDMI audio stops working.
The HDMI interface is no longer seen in the sound settings.
I have to manually run pulseaudio -k to get it running again.

Originally I thought it was because pulseaudio was auto spawning and taking over control of my sound device.
I tried setting autospawn = no in the config.conf.
I tried this for the specific user and globally but the issue keeps happening.

Any ideas how I can prevent this from happening and always have sound through HDMI?

Try opening PulseAudio Volume Control, in the Configuration tab and set any other audio devices to Off.

So long as you don't want automatic switching when you plug in another output device, try:

edit /etc/pulse/default.pa
find <load-module module-switch-on-port-available>
and edit to:
# load-module module-switch-on-port-available
and save.

In other words, comment out the "switch on port available" module in pulseaudio default.pa
