Maybe someone is willing to try this, tested this for nearly 24 hours and audio was working fine.
Edit the files default.pa and arm_droid_default.pa(maybe default.pa is not needed). Both files can be found in /etc/pulse.
Search for the line ‘load-module module-suspend-on-idle timeout=1’ in arm_droid_default.pa and ‘load-module module-suspend-on-idle’ in default.pa. Put an asterisk in front of both lines to disable suspend on unused audio sinks.
I’ll report back if this worked out. So far it is looking good.
