Hi,
While initially working fine, it now no longer is detected on either the latest rPI BookWorm. When trying the “i2cdetect -y 1” no address shows for the card. I tried it on a fresh install on rPI5, rPI4 and even Zero 2 wh. Neither of them will detect it.
As reference, i repeated the whole thing with the Raspberry DAC+ and in all three cases that card is detected properly (showing up at 0x4c)
Of course, I2c is enabled in the settings.
Any hint on what to try next?
Flashed a fresh “Trixie” and retested it all on the zero 2wh. Same result. Only my oled is detected, but not the Raspiaudio DAC 
Very odd. On trixie, when doing
speaker-test -l5 -c2 -t wav
i hear L/R speakers/phones clearly.
But I2Cdetect still does not show the device (??)
Extremely odd. I2Cdetect still does now show the device, but when running miniDexed (GitHub - probonopd/MiniDexed: Dexed FM synthesizer similar to 8x DX7 (TX816/TX802) running on a bare metal Raspberry Pi (without a Linux kernel or operating system)) and NOT defining the (non existend I2C address) by setting it to 0
“DACI2CAddress=0” (e.g. it tries to auto-detect it)
then it actually works. I’m quite happy about this. Still don’t understand it, but happy still
