I've just identified the address of the Codec_PowerOnInitial in our original FW guys. It's 600278A8. Now it's possible to translate it into C and apply it to our compilation.

Of course, I am not sure whether it will fix the audio issue, maybe there is something else that need to be copied from original firmware.

BTW. Knob, and Sid, how does your speaker work? Mine works really badly, and quietly. It's totally useless, unless there is really quiet around. I just wonder if it's my piece issue, or it's normal for this player.

EDIT:
Well, at first I didn't notice that, but this function is exactly the same as in the SDK. It's not the reason of our problem
Perhaps CodecCommandSet is called differently than here just before loading an audio file. What a disappointment
If you have any ideas, which function may be responsible for this, tell me and I'll give another shot.
