My headphone DAC works well with the 1.1 beta and a Raspberry Pi. It’s an Audinst HUD-MX1. I’ve tried only 16/44 files (my CD collection ripped to FLAC) from a Synology NAS via Ethernet. I’ll try to find some 24/96 files and update this post with the test results. I’m waiting for a Wifi adaptor too, so I’ll check the combo.
The DAC is detected and shown in the web UI just booting Volumio. No config. No nothing.
