The error you report doesn't matter. It is because there is no case for EAC3. 
I have an additional patch to use only two channels, and I don't have this 
error. You can use the patch and comment the line:
this->context->request_channels = 2;
and then you don't have the error.
I try with the sample you give to me. If you want you can give me another 
sample.
