Hi, 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 hear anything in my earset, whether I use or not the -d flag. I re-read the pdf documentation and the AUDIO ioctl() implementation in the sources 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 av_71xx cards). 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? Thanks, Nico
