I'm using a FF rev 1.3 card with the latest firmware revision; it works
well and using
ff_al_play I can succesfully decode MP2 and LPCM, but not AC3: I can't
in my earset, whether I use or not the -d flag.
I re-read the pdf documentation and the AUDIO ioctl() implementation in
to find out if the AC3 payload must have the 4 bytes substream header in
the PES payload,
only to discover that at the moment it seems irrelevant (at least for
I also patched mplayer/mencoder to generate correct PES files.
I also made sure to raise the volume (using the appropriate ioctl()).
The result doesn't change: AC3 doesn't seem to be decoded at all,
consequently I can't hear anything.
Does anyone have an idea of what I'm doing wrong?
