Hi
I am trying to do audio playback using ezdsp board for tsmc320c5535, and using the demo code example given with the folder. I tried using it, i can hear 1Khz sound for 5 sec which suggest that headphones are working, but when i try to use audio playback and speak something, there is no sound coming from headphones suggesting that microphone is not setup properly.
I read all the documentation related to this, tried changing code several times. Increased gain, reduced MICPGA resistor values to 10kohm but still couldn't get it to work. I am working on a school project and its time sensitive that i make it working. Also, I tried to change the library files to add more functions but then i couldnt get it to compile properly.
Please let me know how to fix the issue.
