Part Number: TLV320DAC3100

Hi Everyone,

I am using TLV320DAC3100 in our company's prototype board. When I play the audio.wav file, I don't here any sound in my headphones, which I have connected through a 3.5mm jack. 

qt850a:/sdcard # tinyplay audio.wav
[ 83.072432] tlv320aic31xx-codec 2-0018: ## aic31xx_hw_params: width 16 rate 44100

Could you please help in finding out what's wrong?

Thank you

    How are you interfacing with the board? I don't recognize the commands you're showing.

    Thank you,

    Hi Asma

    during playback, dump the tinymix, commands as following:

    # tinyplay audio.wav& // running playback background

    # tinymix

    One more thing, kindly measure the i2s clk wtih scope during playback
