Hi Rern,
before I start here are some information about my project:
I am building a standalone Music Box with
Raspberry Pi 3 Model B Rev 1.2 + HifiBerry Amp2 + original 7” touch screen. There are some hardware buttons installed on the GPIOs for selecting favourite internet radio stations and a rotary encoder to change the volume. The button and rotary encoder function will be controlled by a python script, which starts when Pi is powered up.
I already tried this with other media center like Kodi or Volumio. Kodi was nice and brings a big library for changes by scripting but it was oversized for my purposes and it wasn’t that stable. Volumio … I don’t know why but I didn’t like it.
Now, I discovered RuneAudio for me and I guess it fits best for my purposes. First, I installed from the official download page the version v0.3-beta than I found RuneAudio+Re2, now I am going for the last one. But I guess I need your help or the help of this forum for the best settings for the highest sound quality.
- At system settings I selected for the audio “HifiBerry DAC+” because Amp2 was not listed. As I understood Amp2 is based on the DAC so this selection should be ok, or should I use another? And which sound profile is recommended, or should it be turned off? Actual set up is the RuneAudio.
- At MPD settings “HifiBerry DAC+” is visible as set in the system settings. Here it is recommended to select “Disable” for the best sound quality. But when I do that the hardware volume is set to 0dB as described in the settings but the volume control on the screen disappears and the loudness blows me and all my neighbours away! The only possibility of changing the volume is via SSH and CLI with the command “amixer -M set x%” (by the way my python script will use this command as well to change the volume!). Is this behaviour as described of the system correct? So, is there any difference between the setting “Disabled” and “DAC Hardware” when I want to change the volume?
- Another issue that I noticed; When I change the volume via SSH the screen volume value doesn’t reacts directly! The screen volume value only changes when the actual plying song changes to the next or when the MPD is stopped and restarted again. Could it be possible to make the screen volume value directly changes when the volume changed via CLI command, some kind of coupling them? This behaviour was already in v0.3-beta possible, it would be very good to have it in Re2 as well!
- One last issue; Playing music via AirPlay doesn’t work! My mobile can see the RuneAudio and pairs to it but there is no sound on rune when I am playing music via my mobile!
Hope Rern or someone else can help me with these issues!
Thanx in advance and best regards.
