 Posted: Tue Mar 08, 2005 5:01 am Post subject: KDE init, or perhaps permissions, beep problem [SOLVED] |
 |
|
On a Dell laptop computer I have been unable to get the
PC-speaker (normally beeped via
or typing Control-G in a shell) to beep, in my Gentoo set-up.
[edit]I've edited the title, since I now think that
the problem is either a mal-formed KDE init (7th post) or an
obscure permissions problem.[/edit]
So that I can test to see if the pc-speaker is broken, is there
a way to beep it either from the BIOS or from MS Windows 2000?
(Note: I don't mean the speakers, often controlled by ALSA, that
you'd use to play a music-CD. The pc-speaker is, I believe, on
the motherboard.)

Usually you can get the PC speaker to beep during boot-up (before it starts loading the OS) by holding down a key for a long time during boot-up. The computer beeps at you because it thinks the key is stuck.

Thank you donjuan. Certainly something beeped thrice (upon reboot)
when I "muscled a bunch of keys to the mat".
1: Since it is a laptop box, I can't unplug the music-speakers.
Is there a simple way that I can be sure it was the pc-speaker,
and not the music-speakers which beeped?
2: Does anyone have some hints as to how I can get my pc-speaker
to work under Linux? I do have this module
| Code: | % lsmod
Module Size Used by
...
pcspkr 4300 0 |
installed and running. I also installed `emerge app-misc/beep'.
Executing
| Code: | | beep -f 2000 -l 1000 |
causes no beep. Can something else be muting the pc-speaker?

On all laptops I've come across, there is no separate "pc-speaker". Instead it is another input to what would be the soundcard which would eventually come out through what you called the "music-speakers".
In alsamixer along with the usual PCM, CD, Line & Mic inputs there is another input named something like "PC Speaker", so check to see if there is a slider like "PC Speaker" in alsamixer. If there is, unmute it and raise the slider a bit, and then try to beep the speaker again.

Your BIOS or laptop "soundcard" will set the pc-speaker to a default so it can be heard in case of early startup problems. My guess is when Linux boots and ALSA initialises, it sets the pc-speaker level to the default ALSA settings, which is volume zero and muted. |

Thank you gkmac! On the LC (laptop computer) the pc-speaker was
alsa-muted. I was fooled because, on my DC (desktop computer),
the internal speaker beeps regardless of how ALSA is set --ALSA
just controls whether the beep is also send to the speaker-output
port.
Perhaps you (or other intuitive readers) can help with the remaining
conundrum. I didn't correctly diagnose the problem because, on both
LC and DC, I can only get a "beep" by running the `beep' program;
C-g (control G) produces nothing [which is a problem for me, since
Emacs signals errors by emitting a C-g].
For a while I thought it was a permissions problem but my current
guess is KDE, rather, a particular users init files in ~/.kde/ --but
I can't find where in ~/.kde/ the beep is controlled. Ideas?
(KDE is detecting the C-g, since it momentarily flashes a little bell
icon on the bottom of konsole.)

The bell in KDE can be set via
| Code: | | kcontrol -> Reg&Acc -> Accessibility -> Bell |
I eventually did get the bell working in Emacs on the laptop;
--but I don't know quite how. Nonetheless, I'll mark this as [SOLVED].
