I am working on DRA7xx rev G board. My kernel version is Linux dra7xx-evm 3.12.25.
I am trying to play sound using headphones connector. Kernel logs do not post any errors and everything seems working correctly but I cannot hear any sound.
Logs:
aplay -D hw:0,0 sound.wav
[ 1433.090197] omap-dma-engine 4a056000.dma-controller: allocating channel for 125
Playing WAVE 'sound.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
[ 1435.342125] omap-dma-engine 4a056000.dma-controller: freeing channel for 125
I am able to hear sound using USB headphones.
This is the list of playback hardware devices:
aplay -l
