Re: PC speaker beeps in 2.6.30?

[Adding some more Cc's...]

Am I the only concerned about this?  My 2.6.30 is still
silent w.r.t. old good PC speaker beeps, and I wasn't
able to make it to produce any sound.  Yes, as pointed
out by others there is a control now, in alsa, and I
can hear ugly and scary beeps from my stereo speakers
(when they're turned on and when the control is un-muted).
But that's.. not a solution/answer to the original
question... ;)

Thanks!

Try 2.6.31-rc1.  There was a fix regarding beep frequency.

You mean this one:

     ALSA: hda - Fix digital beep tone calculation

?

Note it's about alsa/hda beep.  Probably to make my new
"alsa beeps" less scary.  But I'm asking about PC speaker --
see the $subject line.  I'm missing PC speaker beeps, not
alsa beeps.

Thanks!

Did you actually try compiling a kernel without CONFIG_SND_HDA_INPUT_BEEP 
set? If you do, does your PC speaker work again?

If it does work again, I don't think there is a bug, at least not in the 
fact that the old PC speaker beep no longer works: if you have a HDA 
soundcard in the system _and_ the driver is loaded _and_ 
CONFIG_SND_HDA_INPUT_BEEP is set, then it seems logical to me that that 
takes over system beeps.
The fact that the config option also existed in 2.6.29 but did not work 
the same seems a minor issue to me.

If your PC speaker still does not work when CONFIG_SND_HDA_INPUT_BEEP is 
not set, then there is something to look into.

This may be a separate issue. On my system the beep sounds "normal". It 
has been changed in 2.6.31-rc1 to a slightly lower sound.

What exactly do you mean by "ugly and scary"? I have the volume for the 
beep set to about 50% because otherwise it is just too loud. Have you 
tried that?

If it really does sound bad, maybe the ALSA developers could look into 
that, but you will have to describe it better (or maybe make a 
recording?).

Yes it works.  Even with CONFIG_SND_HDA_INPUT_BEEP set,
but without the module loaded.  See all the details at

Original issue was that I didn't know what to do.

There was another, unrelated bug, fixed for 2.6.31-tobe.
