[pulseaudio-discuss] The module "module-suspend-on-idle" sounds optional, but is strictly required

I was playing around with disabling suspend-on-idle, since my sound card
makes rather loud clicks and pops on resume.
So, I tried commenting the line
And that works for a little while, but then PA hangs. Every program that
tries to play audio just hangs at 0:00.
I googled a bit, and found this blog:
He described a similar problem with a similar (but not identical)
soundcard. He also had the following conclusion:
What is worse is that if module-suspend-on-idle is disabled there’s no
audio output. When PulseAudio switches the format, the driver is
suspended but never resumes. There are some comments in the PulseAudio
source which suggest that module-suspend-on-idle is assumed to be
available and is responsible for resuming drivers on a format change.
Therefore the work-around for the popping, of disabling
module-suspend-on-idle, isn’t suitable when the audio input format is
not stereo at 48,000 Hz.
He suggested this workaround:
load-module module-suspend-on-idle timeout=604800
Where the idle-time is set to 1 week. This works!
It solved my problem, but my programmer gene is irked by this hidden
dependency. Worst of all, the failure mode is silent-total-fail, which
is not the greatest situation ;-)
So my question to this list: Is module-suspend-on-idle really a
requirement? How difficult would this be to fix?
