Audio passthru Sound Issue

Posted: Thu Jun 13, 2019 1:51 am
We installed the ESP32 ADF and are using the supplied examples with the LyraT. We are using the pipeline_passthru example and changed the LINE2 so the AUX will be used instead of Microphones. So now the sound is being passthru but the sound quality is quite poor. We use speakers and the headphone are both poor quality. IS there a setting to change the quality? Seems like the sound is being filtered.

I also noticed that even if I play audio sample from SDCARD sample, the sound quality is not good. So there must be some CODEC setting that we need to set?
