We have a custom i.MX6 board with S/PDIF and stereo outputs. When we run the speaker test;
speaker-test -t wav -c 1
The sound is repeated as if it is getting mixed with another instance of the same sound. What we hear is something like "front front left left" playing on top of each other instead of "front left" and no matter what we do with -c 1/2. We tried mingling with the configuration files and all and nothing seems to fix this problem. It is the same for both S/PDIF and the stereo outputs so it is not codec related.
Please someone advice what can be wrong.
