Since I didn't get great response on my older inquiry, I'll split this
up and ask one thing that is bothering me more than the issue with
I have my computer connected via SP/DIF to an AV receiver.
With -ao alsa:device=hw=1.1 I can send the audio (also in passthrough
mode) with afm=hwac3, and it is working ok, but the receiver needs
roughly half to a second to play audio.
This not only happens when playback begins, but on every seek, and when
playing back with dvdnav://, on every chapter break (which is very

If I quit a video by pressing 'q' or 'Enter', I sometimes even get the
receiver to detect PCM for a short time (with leads to a loud click or
hiss on the speakers).
So I have two things to ask:
- how to configure (or what to change on) my system to get the silence
on seeking (or channel switching, if I press '#') out of the way? It
seems that mplayer at this very moment doesn't deliver valid AC3 packets
to the receiver)
- if the silence on seek is not easy to fix, what about the reset of the
streams on each chapter break with dvdnav://? This already happened when
I had it connected through analog speakers where the computer did all
the decoding, but it wasn't so noticeable since there was no silence on
seeking/resetting the audio stream (only on very few occasion I could
get a click or hiss noise here and there).
