Not all features can be controlled and set from the HiFiBerryOS GUI. For specific use case, we implemented some hacks that allow you to configure additional things
Note: There is no guarantee that it will work as expected. Some of these hacks might have an impact on parts of the system. We won't guarantee that these will work and there is no support from us. Use these only if you know hat you're doing!
We don't recommend to use DSP Volume control in Roon as it is not compatible with other services. If you want to try it, make sure you don't change the volume in the user interface or with any other service as you won't be able to change it via Roon if you use DSPVolume
Create a file /etc/hifiberry_raat.softvol and restart the system to enable Roon DSP Volume control
We have seen some reports, that some sound cards are not detected correctly in the UI. This mostly happens with DSP sound cards. We're working on inprovements, but if you still see this happening, there's a workaround.
Create a file /etc/hifiberry/config.fixed and add the following line:
DAC+ DSP:
CARD="DAC+ DSP"
Beocreate 4-channel amplifier:
CARD="Beocreate 4-Channel Amplifier"
Put the name of the mixer control to use into this file if it isn't detected correctly
If the file exists, HiFiBerryOS will assume that a DSP is available even if it wasn't detected correctly.
If this file exists, HiFiBerryOS will not start an WiFi access point - even if no network connection is detected.
Featuers will be automatically enabled based on the sound card. In case of bugs, you can enable features using so-called feature files. Just create an empty file in /etc/hifiberry:
Enable TOSLInk input on DSP sound cards
