CCS / LAUNCHXL-CC1312R1：The audio quality of CC1312 is poor, and the data transmitted by TX and RX are inconsistent

Hi team,

I am using C:\ti\Simplelink_audio_plugin_3_30_00_06\RTOS\CC1312R1_LAUNCHXL\easyLink\rfAudioRx.

I found that the sound quality is very poor, but using the Echo project for non-RF testing, the sound quality is very good.

I conducted an experiment and compared the data transmitted by TX with the data received by RX, and found that the higher 8 bits are the same, but the lower 8 bits are different.

Sometimes, the higher 8 bits may be different.

The data on the red line is TX data, and the data on the bottom is RX data. When I send fixed data, the data of TX and RX are the same.

Can you help to check it?

Regards,

Kevin
