Tool/software: TI-RTOS

Hello Technical team,

I am using Tlv320aic3105 codec. With UI interface using Audacity captured the signal of 16Khz wav file and Played back, but I am able to hear recorded signal only in left ear phone. Right ear phone I am not getting any sound.

So could any guide me what I need to do to hear in both.

Thanks in advance,

Jayalaxmi,

I am happy to help! I do need some more information though. What is your current configuration?

are you loading presets? or are you configuring manually via the software GUI?

best regards,
-Steve Wilson

Hi,

Thanks for response.

During Record:
In "preset configuration" selected "on board mic phone to digital output" and powered on left ADC in "Audio input/ADC" , input gain set to 1dB and PGA gain to set 24 dB. All above configurations are set in GUI.

During playback:
In "preset configuration" I have selected the option "stereo playback to capeless Headphone output", DAC powered on in GUI and trying play recorded wav file from audacity.

Please let me know if any information is needed.
Thank you.

Can you confirm that JMP3 and JMP4 are installed on the EVM?
