Hi Team,

        I m trying to test the audio on imx8mmevk. currently flashed prebuilt multimedia images(L5.4.47-2.2.0_images_MX8MMEVK). i can able to play the audio file in the terminal without error but unable to listen the sound(connected headphones at J401 connector). Please check the below logs.

root@imx8mmevk:~# aplay WAV_1Mb.wav
Playing WAVE 'WAV_1Mb.wav' : Signed 16 bit Little Endian, Rate 8000 Hz, Stereo

Hi Ganesh

 

for testing audio one can also try configurations described in

sect.7.5 Audio Mixer (AUDMIX)  i.MX Linux Reference Manual​

https://source.codeaurora.org/external/imx/imx-test/tree/test/mxc_amix_test?h=lf-5.10.y_1.0.0

 

Best regards
