Ultra Optical Input Issue

[Dennis from Venice]

I am streaming Apple Airplay to my Ultra optical in via a Raspberry Pi with Ropiee and a hat for digital coax audio out- t I also have a coax to spdif optical converter since the Ultra doesn't have a coax input.

It worked fine for months and just stopped. Now I can't figure out which component is bad (Ultra, Hat, Converter). Any suggestions ?? The red laser light is on and all connections seem tight.

Have you outputed the pi to another DAC to rule it out and inputed another source into the WIIM to rule it out?

I forgot that my DAC has an optical input....I can test the Pi output by bypassing the Ultra. Thanks !!!!

That did it- thanks again. I narrowed it down to the Allo circuit board. I bought a new board on line for only $24.

And I installed the new hat (JustBoom Digi Hat) just now and it doesn't work either. My Raspberry Pi or the software must be the problem.

I have other Raspi Pi's but they are not an easy switch.

What software are you running on the RPi? Could be a setting got wonky. Also easy enough to burn another SD card and reboot the Pi with that. I find that every now and then a SD card can get flaky.

I took another identical RP4 I had and swapped the SD cards, etc and it now it worked. There was something wrong with the Raspberry Pi. I now have two good RP hats !!!

The software I use is Ropieee and it can be used for Roon, Plex, DLNA, Airplay (1 or 2) and Squeeze.

The RP4 I used was running Home Assistant and doesn't need audio out....so I took the bad RP4 and tried it and it works fine. So the digital audio to the hat was bad in the defective Raspberry Pi but it works fine as a home assistant controller.
