For me the problem was in ALSA, snd-hda-intel module.
$ modinfo snd-hda-intel | grep beep
parm: beep_mode:Select HDA Beep registration mode (0=off, 1=on,
2=mute switch on/off) (default=1). (array of int)
So, "modinfo" says that "beep" sound can be manipulated through "beep_mode"
module parameter.
By default it is "1", but it's not working.
I've modified /etc/modprobe.d/alsa-base.conf:
...
options snd-hda-intel power_save=10 power_save_controller=Y index=0 beep_mode=1
...
Now after reboot pcspeaker works!
I think that this solution may help only for those who uses integrated
audio card (when "beep" sound is produced through audio card).
My config:
