ROSA Linux Bugzilla – Bug 4519
Sound comes with a clacking after wakeup sound system.
Last modified: 2014-10-28 19:30:26 MSK
If a long time there was no sound (any: system, service or user), before playing is fairly loud-clicking.
Solution from keleg
echo 0 > /sys/module/snd_hda_intel/parameters/power_save
I have installed RPSA 2014.1 64bit with "60" in /sys/module/snd_hda_intel/parameters/power_save
and I have no this problem.
Maybe it is hardware specific?

Seems like a known issue the upstream is not going to fix.
"Note that you might hear click noise/pop when changing the power
state. Also, it often takes certain time to wake up from the
power-down to the active state."
I can make powersave disabled for snd_hda_intel by default in the kernel. The users who want it, however, will need to turn it on manually (by writing to /sys/module/snd_hda_intel/parameters/power_save or setting parameters of snd_hda_intel module).
What do you think?
Ok, disable it!

Fixed in the kernel 3.14.22. Closing.
