We put together a SAM board (sc589) with the Eval-Shaudio-ezext kit. We have used the codec initialization code from example from
"Analog Devices\ADSP-21469_EZKIT-Rel1.0.0\21469_EZ-Board\Examples\AD1939_Block_Based_Talkthru_192 kHz\" project.
We can output 24 analog channels (48kHz) in the Eval-Shaudio-ezext kit. If we use only 1 codec (8 channels), it sounds fine. However, after a few seconds (sometimes minutes) the audio output starts crushing and then it fades out (all channels).
Since the audio is clean when we reset the Sam board, I believe the configuration must be correct.
Does anybody experienced similar behavior? Any hint is appreciated.
