Audio file + mediaplayer error (1, -4)

[ocampesato]

Hello,

AFAIK this problem is not posted anywhere on this forum. I would like to play a short audio file (see short code sample below) in Android 2.x, and I encounter this error message:
mediaplayer error (1, -4).

This is what I found in one entry (after a Google search):
"-4 is PVMFErrNotSupported, which also seems to be a catch-all that
usually occurs during prepare() and probably means that OpenCore found
something it didn't like in the stream."

Btw, the audio files play fine from the command line, which launches the Windows Media Player (Windows Vista). I'm sure that there is a very simple solution;(

Suggestions welcome...
Oswald
