[x86_64] PC speaker doesn't work

[Piotr Kaczuba]

Hello!

With 2.6.17 the PC speaker stopped working (2.6.16.20 was fine). The
module pcspkr is loaded but dmesg doesn't show that it gets registered
as 2.6.16 did:

input: PC Speaker as /class/input/input2

I saw a thread about the speaker issue a while ago in which a patch
was posted that made it into 2.6.17 but somehow it doesn't seem
to be enough. Am I missing something?

I'm running x86-64 kernel with 32-bit userspace if that should matter.

Please CC me as I'm not subscribed.

It turned out that the following change is needed when the speaker is
compiled as a module.

You know, I am glad you posted this, as my system bell stopped working
ages ago and I didn't know why (I am on x86 though).

So this post is in case anybody else has this peculiar problem.

I didn't have a CONFIG_INPUT_PCSPKR in my .config, so investigated...

It is cunningly hidden in Device Drivers->Input device
support->Miscellaneous devices->PC Speaker support

Then to get KDE to use it (I used KDE sound to *beep* before I sussed
this tonight), even more peculiar configuration is required:

All now works!  I did really miss the beeps for some silly reason...
