Volume is not changed by the module (Command failed: amixer sset -M 'PCM') about mmm-volume HOT 9 CLOSED

will check the volume change and report here.

Checked. New command works well with RPi & Buster. Thanks. Will add pull request to add this config to readme.md

from mmm-volume.

Maybe your ALSA setup doesn't have PCM.
Try this on your terminal shell.

amixer sset -M 'Master' 10%

If volume is changed, configure your config.js like this;

usePresetScript: null,
getVolumeScript: `amixer sget 'Master' | awk -F"[][]" '{print ""$2""}' | grep %  | awk '{gsub ( /%/, "" ) ; print}'`, 
setVolumeScript: `amixer sset -M 'Master' #VOLUME#%`, 

Everybody might have a different environment, so if presetScript doesn't work, find proper command for your environment and use it.

Thank you for quick responses
Will check today

from mmm-volume.

amixer sset returns the following

pi@raspberrypi:~ $ amixer sset -M 'Master' 100%
amixer: Unable to find simple control 'Master',0

will look for other options

from mmm-volume.

Sorry. I don't know your environment. You need to find a proper command to control your RPI volume by yourself.

from mmm-volume.

I have found this one - this commands 10%+ increases and 10%- decreases by voulme by 10% (percentage could be any)

pi@raspberrypi:~ $ amixer set Speaker 10%+
Simple mixer control 'Speaker',0
  Capabilities: pvolume pswitch pswitch-joined
  Playback channels: Front Left - Front Right
  Limits: Playback 0 - 151
  Mono:
  Front Left: Playback 68 [45%] [-15.63dB] [on]
  Front Right: Playback 68 [45%] [-15.63dB] [on]
pi@raspberrypi:~ $ amixer set Speaker 30%+
Simple mixer control 'Speaker',0
  Capabilities: pvolume pswitch pswitch-joined
  Playback channels: Front Left - Front Right

your environment

i have clean Buster updated/upgraded. RPi 3 B+. usb sound card

from mmm-volume.

So, try this;

usePresetScript: null,
getVolumeScript: `amixer sget Speaker | awk -F"[][]" '{print ""$2""}' | grep %  | awk '{gsub ( /%/, "" ) ; print}'`, 
setVolumeScript: `amixer sset -M Speaker #VOLUME#%`, 

from mmm-volume.

So, try this;

Thank you.
Can't check the volume change right now, only volume set at the start.
But during the start the module is set to the level specified in config.
Also, dark-blue rectangle disappear as needed (from #14 )
Will install telegram later and will check the volume change and report here.
