I am using a Pi4 with this HAT, “Raspberry Pi DAC audio decoder board HIFI expansion board supports coaxial fiber I2S output 3B/3B+4B PCM 32K-192K/32Bit” which was purchased on Aliexpress. I wanted to get the I2s output into my Denafrips Pontus 2 DAC.
The Pi runs Volumio and for the board using the Hifiberry DAC driver or the Generic DAC driver runs fine. I can also switch off I2s and just leave the Volumio settings to “HDMI” output.
Hi-Res music plays fine via Roon. There is an improvement compared to a usb output via a PC. However the only snag is that no sound comes out when playing 44.1/16 files. All hi-res files play flawlessly.
Its a weird problem but its a problem nonetheless. Any ideas how to solve this?
