My Delfina on my A4000 (mounted on Deneb) plays really really nice!
I just use stock Amplifier (updated by BB3) using Delfinampeg.device for decoding MP3 files and output is 16bit Hi-Fi Stereo via AHI using Delfina latest library.
I made a custom Mod mounting some custom audio connectors to the internal input/output connectors which you can check
here and
here.
In one of the pictures you can see a simultaneous usage of:
- CD Play playing AudioCD,
- Amplifier playing MP3,
- EaglePlayer playing Modules via Paula
- My SammichSID playing through Line-In!
Ofc result was an audio mess (LOL) but everything worked just fine
I still haven't tested my Delfina under OS4.1.3 but so far my 99,9% concern is OS3.9
