Vcl and raspberrypi 3.5mm jack

Hope someone can help me here.
Homeassistant installed on Raspberry Pi 3’ use the following code
- platform: vlc
name: speaker_1
arguments: ‘–alsa-audio-device=hw:0,0’
in configuration.yaml for message and was working fine but volume was very low. So i did some research and found a post using the following command to increase volume on the pi.
sudo amixer set PCM — 100%
after I executed the command, the script I used to run announcement no longer worked.
the media_player was playing but no sound come out from the speaker. Can someone help please. BTW, I did reboot the pi and restart HA.

  1. Please format your code so it is readable with proper indenting. This is vital for interpreting YAML. Edit your post then highlight your code and press the </> button in the message toolbar. Or follow the instructions in the blue banner at the top of this page.

  2. Is this the post you were referencing? Volume slider for integrated 3.5mm speaker

  3. Have you tried setting it back to another value? Like 50%?

Thanks tom-1, got it working:
trail and error;
sudo amixer set PCM – -400
will set raspberry pi 3.5mm jack to 92%
sudo amixer set PCM – -10239 will set volume to minimum.
