Haiku will play audio from CDs, but not from audio files on the system itself.
Haiku will play CDs through CDPlayer perfectly fine, and I have my sound card working via the OSS Drivers as with hda the card wasn't even recognized. It is a Creative AudioPCI97 (ES1371). I have tried several different file types, .wav, .mp3, .m4a, and .aac. MediaPlayer and even VLC do not provide sound with any of these, just the time bar moving along as if it were playing normally.
I went VLC's Messages and found this error after an attempt at playing a .m4a:
mpeg_audio decoder : emulated startcode (no startcode on following frame) main audio output : computed PTS is out of range (3715189), clearing out main audio output : PTS is out of range (3715279), dropping buffer main audio output : output PTS is out of range (3715437), clearing out mpgatofixed32 audio output : libmad error: bad main_data_begin pointer main audio output : audio output is starving (103177), playing silence
Can anyone provide a fix/tell me what is going on here? Help would be appreciated.
Thank you.
