Hi all,
I have the same problem as Karel on a customers board, headphone circuit works fine but speaker amp will not do anything. If I set register1/30 to 0x03, then register 1/32 stays at 0x86 and the status register (0/37) indicate that the class-d driver is powered up but I get no sound from the speaker. I have confirmed that the speaker is 8 ohms.
