Volumio Development Bug reports
1

Hello
Hifiberry has released a wonderful small amp an easy to install amp with 2x25W

-> Configuration
-> Productlink

The Amp works with volumio. Only the Volume Settings makes Problems. The Volume in the Webui shows allways 100. I can’t change it.

I can set the volume with the shell command:

amixer sset Master 100 -> very silent

amixer sset Master 200 -> very loud

amixer on the shell shows the following:

root@volumio:~# amixer
Simple mixer control 'Master',0
  Capabilities: volume volume-joined
  Playback channels: Mono
  Capture channels: Mono
  Limits: 0 - 248
  Mono: 100 [40%]
Simple mixer control 'Channels',0
  Capabilities: volume
  Playback channels: Front Left - Front Right
  Capture channels: Front Left - Front Right
  Limits: 0 - 248
  Front Left: 200 [81%]
  Front Right: 200 [81%]

aplay -l on the shell shows the following:

root@volumio:~# aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: sndrpihifiberry [snd_rpi_hifiberry_amp], device 0: HifiBerry AMP HiFi tas5713-hifi-0 []
  Subdevices: 0/1
  Subdevice #0: subdevice #0
root@volumio:~#

Please implement support for this beautiful amp! … and give the hints how i can get it to work until 1.42 with support for the amp cames out :mrgreen:

Thank you very much for Volumio!

Try to edit /etc/mpd.conf and place “Master” as mixer control! Let me know

Works as expectet . So easy!

The usable Range for my Speakers is 20 to 75 (Volumio GUI Units). Feature Request :slight_smile: -> set the limits in the Gui?

Thank you for the fast support!

Great!

Thank you, you made my day. :slight_smile:

I was able to configure it. For the first time the amp is running perfectly together with volumio!

Cheers,

Well, if you search the web you’ll find tons of info / how to / help for Linux, nano etc…
To be short : you can edit the file you want with nano. But you need to be allowed to do that if you want to change a “system” file like mpd. conf. This can be achieve with “sudo”. Before save the file (in case if something goes wrong) sudo cp /etc/mpd.conf /etc/mpd.conf.old and edit with nano sudo nano /etc/mpd.conf . Once here, modify what you want, save it and exit (Ctrl x). To apply you can sudo service mpd restart or reboot your device… :wink:
