Can you please save the content below to some file (like ~/

for d in $(aplay -L | grep ^[a-zA-Z])
    echo Testing device: ${d}, press ENTER to continue
    amixer --device "${d}" set Master Playback 100%
    aplay --device="${d}" "${SND}"

And then:

  1. Open a Terminal
  2. Run chmod +x ~/
  3. Run ~/

This will iterate over all your ALSA Output Devices, set them to maximum volume and tries to play a simple wave file. Please provide the output and name the device which (if any) provides output.


Simple mixer control ‘Master’,0
Capabilities: pvolume pswitch pswitch-joined
Playback channels: Front Left - Front Right
Limits: Playback 0 - 65536
Front Left: Playback 65536 [100%] [on]
Front Right: Playback 65536 [100%] [on]
Playing WAVE ‘/usr/share/sounds/alsa/Front_Left.wav’ : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
Testing device: null, press ENTER to continue
this thing appears, i press enter like 20 times but nothing happens


It seems that there’s a problem with the audio driver, please run:

aplay -l


aplay -L

This will list the Hardware Audio Devices and it’s channels. To me it looks like that your sound card isn’t initialised properly at boot time.
