I use pulseaudio on my laptop. I start it by `start-pulseaudio-x11` in something like .xinitrc (I use a standalone wm with lxdm). When I resume from pm-suspend, the system beeper issues several beeps; when I open a urxvt, a bash completion failure will issue a beep too. However when any program that talks to pulseaudio starts (or try again to talk to it), e.g. start pavucontrol, everything is normal again.
My guess is that what happens is that pulseaudio blocks the sound device, and that's the reason you don't hear the beep when it is running (i.e. when sounds play). Disabling PA as Ralf suggests would in this case not help at all, and likely just make it worse (I wish people would stop suggesting to disable PA regardless of what the problem is, in most cases this is not going to make things easier). If I understand correctly your underlying problem can be solved by blacklisting the pcspkr module, that should make sure the kernel will no longer beep. Cheers, Tom
