Unfortunately, I can confirm that stock 2.6.38 does NOT resolve the pops on suspend and resume.
OK, then did you try to set option power_save_controller=0 for snd-hda-intel?
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?
The actual value is shown in /sys/module/snd_hda_intel/parameters/*.
