I use a combination of the DAC+ADC pro with the AAMP60 on a Raspi 3B+
Everything worked fine until the last hearing of music 2 days ago. Now the DAC seems to be dead.
"pcm512x: probe of 1-004d failed with error -121"
i2cdetect find the ADC on 0x4a but nothing else. So the i2c bus seems to work.
Any suggestions beyond using a trash box on its purpose?
