Part Number: TLV320AIC3100EVM-U
Hello,
when i plugged this evm the first time into my pc, then the drivers seems to be correctly installed. After that, i can choose this evm for playback/recording. When i start the "CodecControl" programm, then the evm becomes initialized and the playback is working, also it seems that as default the DIN=>DOUT loopback is active, because i can record to music i feed into the codec. So far so good.
I adjusted and verified the registers with the "Register Inspector" so that the microphone input should be deliverd to DOUT, but this isnt working! The most strange thing is, that the drivers/amplifiers/terminals for playback/recording paths are active after the basic initialization, because i can hear audio on the headphones (also checked page 1). But when i check the page 0, then the ADC/DAC flags are all 0 which is obviously wrong...
What are the steps that must be done, so that instead the loopback the mic input can be recorded?
Thanks and kind regards,
Lukasz
