support for Allo Digione ?

bsheckler · April 2, 2019 at 9:18 AM

Hello,

I am in the market for a second RPi Audio HAT, and I'm not that fond of USB in my audio path.

I am reasonably happy with the my RPi3B+Hifyberry Dac+Pro.

I am curious if I will hear a significant sound improvement going to the RPi3B+ and the Allo Digione digital output module.

More importantly for this forum, I am curious if there is good support for this HW combo in LibreELEC ?

I thought that I saw it was official supported when I joined, but was just checking again before pulling the trigger.

Thank You for the help,

Bil

I don't have an Allo Digione card myself but it should work fine with current LibreELEC versions.

The main difference to the Hifiberry DAC is that it'll allow you to use AC3/DTS passthrough if you connect it to a surround receiver.

The Allo card doesn't seem to have an optical (Toslink) output though. This can be very helpful for fixing ground loop issues - the Hifiberry Digi cards (which are also significantly cheaper than the Allo card) and several others have this feature.

With S/PDIF digital output audio quality will be mainly determined by your receiver / DAC. As this eliminates the analog connection to your receiver / amp and the probably more noisy power supply on the RPi audio quality should be a bit better. As you seem to have been happy with your Hifiberry DAC I wouldn't expect a significant improvement though.

so long,

Hias

Take into account to buy an HDMI audio splitter instead. It makes you indepandant of any driver issues, and you'll get an optical out for less money.
