Tool/software:
Hi，
We using TI TA1000F_V1.0_CODEC+AMP.pdfLV320AIC3104-Q1 (MPN: 6PAIC3104TRHBRQ1) as the audio codec, combined with internal AMP to form the audio circuit. Circuit diagram reference: A1000F_V1.0uCODEC+AMP. pdf
1. Are there any differences in the vehicle specification models, registers, and hardware design between TI TLV320AIC3104 (non vehicle specification model) and TLV320AIC3104-Q1 (MPN: 6PAIC3104TRHBRQ1)? If so, are there any relevant documentation explanations;
2. Based on the TLV320AIC3104-Q1 (MPN: 6PAIC3104TRHBRQ1) vehicle specification model, after executing our current demo, both the RIGHT_LOP/LM+AMP pathway and MIC can work normally. But connecting LEFT_LOP/LOM to the front end of AMP does not work, as shown in the figure below. Investigate the factors that affect signal quality through wiring, and no matter how the right channel is connected, there is no problem. Disconnect the link and test that there is no audio signal output from LEFT_LOP/LOM. The software is configured to output both left and right channels. Please help analyze the possible reasons and investigation direction. The software uses a third-party SDK and black box, and some configurations cannot be read. However, it can be confirmed that both left and right channels are not in silent mode.
