ALSA Beep control

Error: "amixer: Unable to find simple control 'Beep',0"

After installing alsa-utils you may find that it may not include the Beep control. When you run amixer you get the following output.

# amixer -q set "Beep" 50% unmute
amixer: Unable to find simple control 'Beep',0

The problem is likely due to the fact that the driver, snd-pcsp is black-listed and/or not loaded. Check any of the usual kernel module black-list files. ALSA stuff is usually here, /etc/modprobe.d/alsa-base-blacklist.conf. Comment out the following line.

# blacklist snd-pcsp

Next load the module.

If that fails try '''apt-get install beep'''.

Sometimes '''snd-pcsp''' won't work, but '''pcspkr''' module will work. You can't have them both loaded at the same time. Try the following.
<pre>
modprobe -r snd_pcsp
modprobe pcspkr
echo -e "\a"
