Shoto,Can anyone advice or know good guides on basics of using Rpi4 as a DAC source?
Specifically using Rpi as a 'Network DAC', Windows PC or laptop is used as normal but the audio output is somehow send to the Rpi over network and to play automatically? Or how about same thing but over bluetooth?
If this is not possible, too difficult or has too much latency to work well (for videos etc.) then what about the Rpi with local storage and playback but controlled over the network or bluetooth, either with PC or mobile?
want to learn about what options there are.
Volumio allow something close to the first option. PC controls Volumio Rpi over network, Rpi access PC storage over network.
wont be as seamless as a 'network DAC' but still ok for music if no other option
getting closer again to the solution: https://volumio.github.io/docs/User_Manual/Stream_audio_to_volumio
If I understand your question, this is really easy.
If you want to use a Pi as a streamer you can use Volumio to stream from a NAS or what I do is load my music files (~250 - 300 CDs) onto a microSD card and store them onboard the Pi along with the OS and Volumio image.
In the configuration shown, I’m using wireless networking.
You don’t need a Pi 4. I’m using a PiZero W2 which has more than enough power. A Pi 4 is a major overkill for this application. (I just checked my Pi and the average CPU loading is 14% with a system temp of 42’ C. It’s not even breaking into a sweat doing this!)
I use Samsung High Endurance SD cards so no worries about longevity. A 64gb card costs around $14 and I still have 30 gb of free space.
I can also stream radio stations from Volumio as well as stream audio from my phone or tablet via Airplay.
My setup today is a Pi Zero W2 => Topping E50 DAC (via microUSB to USB B cable) => Topping PA 5 amp => Elac Reference DBR62 speakers.
(That’s the Pi Zero W2 on top in the Flirc case.)
I typically control this from an iPad or iPhone. (I can do the same from my laptop but never do.) The Topping DAC has a remote as well to control volume and source.
Works great.
