I am setting up a computer running CentOS 4.2. It's a week-old install so pretty clean. I have a tcl/tk program that is supposed to monitor humidity and beep when the humidity reaches a certain level. If I remotely log into the computer and export the display, when I run the program and the humidity alarm is triggered, I hear the beeps on my local speakers (as I should). When I log in on the console of the CentOS computer and run my program, when the humidity alarm is triggered, there are no beeps. I have tested the speakers and sound on the computer and everything is working just fine. I have tried xset b on/xset b off and it works correctly on the remote terminal but again, no change on the local console. I have tried this under gnome and openwin (olvwm)[ -- don't ask, we need to have it installed] and no luck on either side. I have tried control+g, echo "\007", echo "\a', and none work locally. If I log in on the commandline (init 3), it doesn't work either.

I forgot to mention that I tried messing with modprobe but that didn't help either (modprobe -l pcspkr ;modprobe pcspkr;^G).

UPDATE: 10/27

Ok, today we opened the box and looked for the internal speaker, since the computer does not produce POST beeps either. Turns out this case does not have a built-in speaker. When we hooked one up to the motherboard, bingo it works, too bad we can't use that speaker. Now my question is how do I direct the output for the internal speaker to the sound card? And is this window manager dependent?

Does anyone have any ideas?

Thanks!

You don't. You hook up a pc speaker to your motherboard pc speaker connector. It's a separate entity and bios controlled. I2C I believe it's called talks to your BIOS and tells the speaker to beep. It's low level kernel stuff and can't play mp3's when the ocean swells onto your pc, as far as I know. But, there could be a program like gkrellm that can translate the alerts to sound files. But that sits atop the GUI and won't run if the GUI isn't.

Thanks for the suggestions. I will try them and see what happens.

Thanks a lot!
