TLV320AIC3104-Q1: Need to understand about Mixer paths and ACDB tuning for the audio

Part Number: TLV320AIC3104-Q1

Hi Team,

Need your help to understand the acdb tuning for the audio and audio codec tlv320aic3104 and processor IMX8MM-evk.

Do we need any acdb-loader file for the audio calibration tuning?

Related Mixer Path:

If I'm connecting 2 speakers only to the LEFT/RIGHT_LOP and LEFT/RIGHT_LOM , What are the routing needed in code apart from driver file.

Do I need to configure speaker routing separately in codec file or DTSI file?

so the question is How to route audio through 2 speakers with routing. can you share snippet or any reference for mixer paths

Thanks.

Hi,

You might find answer on ACDB online as this is system specific which I'm not familiar with.

As regards to the audio output path to left or right LO paths, attached diagram shows the respective register you need to set to enable the path.

Regards,

Peter

Thanks for your reply.

I have the same pdf with me.

I wanted to know about, when to and how change register value.

You can change them through your I2C transaction by writing the respective registers in the block that you want to update.
