I tried this by adding the following line to 
/etc/modprobe.d/alsa-base.conf:

   options snd-hda-intel power_save_controller=0

and after a reboot, I still get the same pops on suspend and resume. Is 
there some way to check dynamically whether the settings of the driver 
match what's configured here?

Cheers, Chris.
