pcspkr only loaded after waking up from sleep

My laptop only rings the error bell (the PC speaker) after waking up
from sleep.  It does not after a fresh boot.  Or maybe the issue happens
at random.

It seems that pcspkr fails to register properly on boot:

--8<---------------cut here---------------start------------->8---
> dmesg | grep pcspkr
[    2.109740] input: PC Speaker as /devices/platform/pcspkr/input/input5
[    2.127371] Error: Driver 'pcspkr' is already registered, aborting...
[    2.281487] Error: Driver 'pcspkr' is already registered, aborting...
...
[19213.561915] Modules linked in: msr [...] pcspkr [...]
--8<---------------cut here---------------end--------------->8---

19213 is after waking up from sleep, the modules get re-linked I
suppose.  It works from then on.

Anyways, I'd like to turn it off for good.  Is the following the right
way to go?

  (kernel-arguments '("modprobe.blacklist=pcspkr"))

Anti-trust laws should be approached with exactly that attitude.

Yes, it is.  I recall I also needed to blacklist "snd_pcsp" module to get
rid of this annoying beep (so I have "modprobe.blacklist=pcspkr,snd_pcsp");
although it was several years ago, maybe it is not necessary anymore.

Thanks!  Any idea why the module does not load properly at boot time?

Sorry, no idea :-)

Just rebooted with my new pcspkr-less system configuration, and now I have
no sound at all!!

Weird... I'll keep investigating.
Otherwise a `xset -b` or `amixer set beep 0% mute` should be enough.

Apparently there are various ways to control the beep.  Check out:

Indeed, that's where I got the above two commands from! :)
