I purchased the RaspiAudio Ultra+ from Amazon because it was advertised as compatible with Volumio.
Unfortunately, I have yet to get any audio from the device using Volumio.
After half a day of reading, testing, and troubleshooting, I installed DietPi and I have managed to get audio from the Ultra+. At least I know the device works properly.
Coming down to my question.
How do I get Volumio working with the Ultra+?
I think I have reinstalled Volumio 3.251 almost 20 times and tried countless proposed solutions found on this forum and others.
I really want this to work, but I am loosing hope.
Is the Ultra+ not compatible with Volumio?
Should I replace it with a Mic+ or other DAC if I am planning to use Volumio?
I have tried this install guide, both method 1 and method 2.
Maybe combining the knowledge from the first solution you provided with the knowledge in this solution will get it working.
Worth another look anyway.
Performing Method 1, I get audio, but it is quiet and crackly and the ultra+ module get very hot in just a couple minutes.
The reason it didn’t work the first time I tried this solution is because I tried to use the I2S DAC settings instead of the regular output device.
Performing Method 2, I managed to get audio after learning the above and the ultra+ module does not get hot.
The problem I discovered is that only some audio streams appear to work.
I can play the web radio stream labeled “ANTENA1 | 94,7 FM” but I randomly tried about a dozen other streams and received the error message in my June 9th screenshot.
I tried installing the Spotify Connect2 plugin.
I can connect my Spotify to it, but no audio and when I change the volume level, Spotify disconnects and returns to playing locally on my phone.
