I currently run a setup with squeezelite (by squeezeplug) on Kernel 3.18.x and the AMP+.

My question is regarding the hardware volume control:
Does anyone know if squeezelite can use the AMP+ integrated hardware volume control?

When I set the volume adjustable for the player on LMS, I cannot see any change on the amixer volume when I change it over the LMS. Does that mean the hardware volume control is NOT used?

If squeezelite cannot control the AMP+ hardware volume control, I guess the best option is to set 100% on squeezelite and adjust the volume via amixer (e.g. script). Am I wrong?

Thanks a lot!

  Hi,
  
  I don't know if squeezelite can control an ALSA mixer control. If not, the best thing is to set the volume to 100% and user alsamixer - exactly as you said.
  
  Best regards

  I setup v1.8 of squeezelite to control the AMP+ hardware volume using the -V commmand line parameter. The -L option will list available controls. I can see the volume changes in alsamixer when controlled from iPeng as per conversation in this thread:
  
  
  
  The only niggle I have noticed is that the usable volume range is between 15 and 45 as displayed by squeezeserver. I'm investigating if I can rebase the squeezelite volume range.
