Welcome @denvd1
if you plan to use Android on your device, you can install those respective apps as you music streaming service, volumio is just a firmware dedicated to Audio playback, there is nothing that confines those app to it…
to use the the sound output between I2S GPIO pins or HDMI output with your own external device, you will need to switch the Audio output from within the device settings, hope it helps
to be exact, Android or the device can limit it to 48kHz on it’s own outputs, and on my Android smartphones and MiBox S, the Tidal app doesn’t recognize the Tone2 Pro.
But there’s no bitrate limit, and if I use USB Audio Player Pro on all my Android devices, they see the Tone2 Pro perfectly and send the raw stream to the Tone2 Pro, with no limit on samplerate and bitrate.
Also, in the “UAT connection mode” item, put a tick in the “Connection quality” item in order for the sound to be output with the maximum resolution of your audio card.
