Disable speaker Beep in Debian + PulseAudio
I hate that annoying beep, that drives me crazy! Disabling the pcspkr kernel module and blacklisting it from being loaded should help:
# echo 'blacklist pcspkr' | sudo tee -a /etc/modprobe.d/pcspkr.conf # sudo rmmod pcspkr
That only/just turned off beeps in my console, but some Xorg applications still made them. In order to turn them off, first we need to identify our soundcard-id.
List all audio devices:
# aplay -l
That brings something like this:
**** List of PLAYBACK Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: STAC92xx Analog [STAC92xx Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: PCH [HDA Intel PCH], device 3: HDMI 0 [HDMI 0] Subdevices: 1/1 Subdevice #0: subdevice #0
The device i want to disable the beep from is “card 0”. Lets do it:
# amixer -c 0 set Beep 0% mute
Replace/use “Beep” or “PC Beep”, that depends on your soundcard and alsa configuration. The output should be something like this:
Simple mixer control 'Beep',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined penum Playback channels: Mono Limits: Playback 0 - 3 Mono: Playback 0 [0%] [-18.00dB] [off]
To be sure i also invoke a
# sudo alsactl store
Reboot and your’e done!
