Hello
I would like to inquire because the audio in the custom board is not currently working.
I am using the TLV320AIC3106IRGZT + Amp circuit TPA3111D3111 and it is connected to a speaker (8Ω, 8W), but it does not work.
The source program used the existing AM62 EVM, and the EVM earphones were confirmed to work by directly listening to the sound.
For the custom board circuit, the TLV320AIC3206 was taken as is except for the output, and the AMP circuit was added.
TLV320AIC3206 output changes: HP(L,R) OUT output-> MONO_LO+, LO-
I am attaching the Auido waveform and board circuit, so please review why it does not work.
The difference in the circuit is that the address setting pin goes to High on both sides,
Two MLCCs (C586, C588, 680nF) on both ends are removed before AMP output.
When entering the aplay -l command, the screen is as follows.
The screen output when a speaker sound operation command is given is as follows.
Even if I turn the AMP variable resistor, there is no response.
It doesn't seem like it's not coming out of the CODEC IC output, but I don't know if the AMP IC circuit is wrong.
Please reply.
thank you
