Dave, thank you for the answer. Changing value of /sys/module/snd_hda_intel/parameters/power_save on-the-fly didn't help me. But definitely it's something about power saving. Because if I suspend/resume laptop on AC power - there is no problem with sound. If I do the same operations on battery power - sound is popping (I checked with aplay /usr/share/sounds/alsa/Front_Center.wav). If with "bad" sound I connect laptop to AC power - sound became normal. So maybe this is something in /sys that can help me. I will try to find it. I updated BIOS to latest version - it didn't help. I also checked with Kubuntu 12.10 live cd - there is no sound at all after suspend on battery power (after suspend on AC power it's all ok)
