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).
