Hello,
Here is what i did with Volumio, i would like to keep it simple as i have already an excellent external DAC (Nuprime DAC-9)
The goal was to store local Music and stream it to the DAC with a bit perfect USB output, no need to add something more, no hat, no reclock as today’s DAC are usb asynchrounous (no jitter possible)
Volumio is intalled on a 8gb SD card and i plugged a 256gb SSD External Drive on a raspberry 3B+
on volumio, i have installed crontab and rclone, nothing more is ordered to avoid conflict and update problem.
My music is store on my computer and sync to google drive.
With rclone i have sync google drive music folder at each Volumio reboot to a Music Directory.
everything is in a nice aluminium box
Alim is an industrial simple one RS15-5 (5v 3A) as the rapsberry 3B+ is not able to manage more than 2.5A
no need to to more hole, raspberry is connected to wifi network, i have have to plug the DAC to the external USB port. And the Nuprime is automatically detected.
I have disable hardware sound control, so i’m bitperfect
