A Carafe of Ubuntu
Hi everyone! My alert signal doesn't seem to be working. It is enabled in "sound settings" even giving options for bark, ding, drip, etc... My computer doesn't beep when I type:
echo -e "\a"
Is something broken? Am I doing something wrong? I am working through the Bash script tutorial in my signature.

in Sound Settings, is Alert Volume set and not muted? If so, does pressing Backspace at an empty prompt make the alert sound? If not, check the "Terminal bell" setting in gnome-terminal (or your terminal of choice).

Hi crdlb. Thanks, I wasn't really aware of the terminal settings. All the settings look good, I should really be hearing a bell! Maybe this is a bug with my system?
Alert volume: slider at about midway
Mute: box not checked
Backspace at empty prompt: no sound
Terminal bell setting: box checked

Is it completely silent? My computer emits a click when it's supposed to beep, and this has been the case since I installed Ubuntu two years ago. During one release, it worked but then stopped again.Originally Posted by Stovey
Once, when I experimented with generating sine waves programmatically and playing them, I found that I got that same click in some circumstances, something to do with left and right channels. But my computer is able to play sine waves, I know that much.

Yes, it's completely silent, not even a click.

if your system is using ALSA, you can access some settings from the command line...
you can press 'esc' to exitCode:$ alsamixer
one of the items may be beep, which can be muted/unmuted with the 'm' key
while(!(succeed = Try()));
Double check that it isnt blacklisted
Open the file '/etc/modprobe.d/blacklist' and look for a line like 'blacklist pcspkr'

Thanks everyone. Sure enough the beep and the speaker were muted in the Alsamixer. I enabled them, but still no beep!
Here are the files in modprobe.d:
alsa-base.conf
blacklist-ath_pci.conf
blacklist.conf
blacklist-cups-usblp.conf
blacklist-firewire.conf
blacklist-framebuffer.conf
blacklist-modem.conf
blacklist-oss.conf
blacklist-rare-network.conf
blacklist-watchdog.conf
I looked at alsa-base but it didn't really make sense to me.
The blacklist-oss is a dynamic link:
lrwxrwxrwx 1 root root 41 2011-10-13 17:07 blacklist-oss.conf -> /lib/linux-sound-base/noOSS.modprobe.conf
Would you mind explaining to me what modprobe is? I'm new at this. It looks maybe like a workaround for hardware incompatible with the OS?

Are you sure you mean the modeprobe.d file not the blacklist file?
The blacklist file is used to blacklist certain loadable kernel modules. The pcspkr is the most common entry people ask about. Usually because they want to turn it off!

FYI, although you may be expecting 'beep' to come from an internal speaker hidden inside the computer, it will probably be outputted from your computers external speakers. Make sure you have speakers attached and the volume is turned up.
