Troubleshooting • Pi4 piCorePlayer 11 connect to FiiO Warmer K515 DAC problem

Hi,

My first post in here ....
I have been using Pi4 with piCorePlayer for a long time and works fine.
Couple days ago, I got a new FiiO Dac, it's the Warmer R2R dac K515 (has the 2 big meter in the front).
I spent 2 days already and am unable to connect to this DAC.

I tried:
- upgrade and use current piCorePlayer 11
- update update the latest Bootloader

When I power up with everything, I do not see Pi4 show up in my Network Admin connected machine (Orbi).
In Squeeze Lite player output option do not see any output option for FiiO.
Chat GPT suggested a bunch of things I tried but didn't help.
I am looking for real people suggestion and experience.

The Dac does work if I plug my Macbook directly usbc out to usbc input. Just try to figure out how to connect from Pi4

The below snippet was from earlier piCorePlayer version where everything was fine and first attempt to connect to the FiiO without success.


Thanks!
Dom
