[MPlayer-users] Still problems with 24-bit audio?

[Martijn van Beurden]

Hello everyone,

I still have some problems with playing 24-bit audio via mplayer. I get
this error:

Well, I did report, as the error message asks :) If I don't break it
it'll keep displaying this error. The samples which have this problem
can be downloaded here: http://www.2l.no/hires/index.html. I decoded the
24-bit/96kHz FLAC files, playing these don't cast this error, probably
because MPlayer says they're 32-bit signed:
