I'd like to use raspberry pi 3 + ubuntu for an "audiophile" sound. I have a m2tech Hiface Evo card that is connected to an external DAC. I tried to use mpd + alsa with good results, but I would try to compare it with the Rhythmbox player using Gstreamer. Now, the audiophile sound provides, among other things, the disabling of the volume. Hiface hasn't a hardware or software volume control. In the mpd's config, however, I disabled the mixer with the value "none" and so I am sure I haven't the volume control (in various mpd's front-ends the volume bar is either disabled or has no effect on the sound). I would like to achieve the same result with Rhythmbox and Gstreamer, but I can't find the right command on the web documentation. The Rhythmbox's volume control has effects on reproduction. I precise that I have disabled Pulse and that I use alsa with Gstreamer. How can I disable the volume on Gstreamer (or Rhythmbox) settings? Thanks in advance!
Try to remove, update and install the drivers for it.
sudo apt-get update
If you also want to delete your local/config files for rhythmbox then this will work:
sudo apt-get purge rhythmbox sudo apt-get autoremove
sudo apt-get remove rhythmbox sudo apt-get remove --auto-remove rhythmbox sudo apt-get install xxxx
While some may find it useful to have music players listed in the sound indicator menu with individual controls, installers of multiple software may want to blacklist some media players from appearing there. It can be done with this simple command, or edited in dconf Editor.
First, open the Terminal, then execute the following code:
gsettings set com.canonical.indicator.sound blacklisted-media-players "['rhythmbox']"
