The audio/music player on my HTC Hero locks up immediately when it starts. As a result I cannot preview any sounds or play any music unless I stream with pandora or something. I have installed another music player app, which is fine for music, but the default player remains the one that locks up, so if I click an audio file to preview it, that app comes up and locks. Is there a fix for this? Can I somehow set another 3rd party player as default?
