TLV320AIC3254: TLV320AIC3254 volume issue

Part Number: TLV320AIC3254
Other Parts Discussed in Thread: CC3200

Ask about the TLV320AIC3254 volume.

We have purchased the Ti Audio Booster Pack and are working on the Project.

The hardware configuration consists of CC3200, TLV320AIC3254 Codec, Mic and battery on one board.

In the example of CC3200 SDK, if you set the sound size to MAX while referring to the wifi audio app, the sound volume is very small.

The wifi audio app seems to have a register setting based on the ear mic. Can you tell me how to set the register for mic on board?

I have very little experience with Audio Codec.

Please help me.

    Hi, David,

    I am not familiar with the Wifi Audio App, but from the codec point if view it is possible to change the input PGA gain. Can you please share more details about the reference to set the volume gain so I can see if the registers of the codec are properly set?. 

    If you have a way to directly write the codec's registers, I can point to the gain register to adjust the mic gain. 

    Best Regards,
