I am using a tlv320AIC3106, and trying to configure HPxCOM as an independent output (from DAC_L/R1).
After sent configuration data to 3106 via SPI, the sound signal doesn't go through DAC_L/R1 -> HPxCOM. On the other hand, when select DAC_L/R2 and HPxCOM as independent output, the sound can go through it.
According to its manual, when HPxCOM (Register R37, R38 as 0xe0, 0x10) set as independent output, it should pass the output of MUX (controled by Register R57 - 0x80, R68 - 0x80) to HPxCOM. But the signal couldn't go though it. When changed DAC outputs to DAC_L/R2, the signal went through.
I set the 3106 registers as below:
R37 - 0xe0,
R38 - 0x10,
R41 - 0x00,
R43 - 0x00,
R44 - 0x00,
R57 - 0x80,
R68 - 0x80,
R58 - 0x09,
R72 - 0x09,
Is there anything I set wrong? and do I miss anything?
Regards,
