Re: Couldn't parse the format of .wav?   
wav files don¹t typically have ID3 metadata, only mp3 and aac do.

Do you have the wav_parser on your system?  Did you start io-media-generic
with MM_INIT set and pointing to the directory where your mmedia DLL¹s are?

In this doc it shows how to set the dlldir (which is the same as MM_INIT)
and start io-media:

Hi Dan!
     I have checked the MM_INIT as you said ,the MM_INIT is ok.and there is  wav_parser in the path of dll/media/.
Otherwise ,I want to said that the mp3 file can be parsed correctly,I can get the song metadata.but the wav can not be 
parsed,the metadata value is null.
the track log is :
io-media-generic/trackplayer: Couldn't load the wav_parser filter (based on the
parser tag)
