In my previous post I have described my problems, now I'm in this situation: 1. wm8974 configured as slave, sam9g45 master generate a 12Mhz clock con MCLK, the SSC1 generate BCLK and frame signal with right frequency 22khz, 44.1khz etc. (I know that is't better to use wm8974 like master but for now I use this configuration...) 2. I try to play a mp3 (with mpg123) o a video (with mplayer). I see the signal generated by MCU, and the DACDAT signal. 3. I use the default configuration of wm8974 registers, I put the volume to 100%, the result on headphone output is noise, only noise.... Stopping playback the noise stop so I think that I'm playing a sound but no output!! Someone could help me? I don't know if I'm in the right list.... could you suggest me another one better for my questions? Best regards Michele
