How to control audio volume on Raspberry pi 4 + hifiberry DAC+ ?

Hello, i'm posting this because i would like to ask you some questions about DAC+ and how it works with other parts. I want to build a speaker with car audio components. I have a car amplifier from Focal, it's name is Focal FD-2.350. It's a stereo amplifier with RCA audio input. I would like to connect it with a Hifiberry dac+ coupled with a raspberry pi 4 with OSMC. I know i can control audio volume on the amplifier, but it only needs to be set one time, the amp technical sheet tells that i need to put my audio device at max volume, then i select my max audio volume on the amp. So how can i control the audio volume of the whole speaker without touching the amp? Is there any volume control on OSMC or raspberry or Hifiberry DAC+ ? I've red many things about hardware volume control, software volume control, OSMC volume control, but i don't fully understand so i'm asking you to be sure. I hope you know how to control the RCA audio output volume that goes to the Focal amp. Thanks for reading my post i hope you'll answer me ^^

  Hi,
  
  The DAC+ Standard and Pro provide an ALSA volume control that you can set using "alsamixer" or similar tools. I'm not sure what volume control capabilities OSMC offers. However I would expect that I can use the ALSAvolume control. Unfortunately I haven't used OSMC for a very long time and therefore can't say exactly what you need to configure.

  Best regards,
  Daniel

  Hi,

  Ok so i need to install alsamixer on my Pi as well as OSMC ? With this program how can i change the volume ? Do i need a remote control ? Is the control accessible on OSMC ? I didn't tell but i will use the official 7" touchscreen do that i can use OSMC directly on my speaker. It's a party and home speaker. That's why i would prefer to have an easy to use volume control, i wanted to have a dial or +/- buttons at first but i don't think it's possible for me with the DAC+.
  Thanks for the answer and best regards,
  Edgar

  The tools is probably already installed. You can just login via SSH and run alsamixer from command line. Unfortunately I don't know OSMC in detail.
  It's probably the best to ask specific OSMC details in the OSMC forum.How to control the volume has nothing to do with the DAC+, that features the software your're using (in your case OSMC) will provide.
