[MPlayer-users] Problem with using alsa/hwac3

I've finally managed to get hwac3 working nearly correct but there's one
problem left: I get some occasional stutters. It's not jerky like in lacking
cpu power or asynchron - the audio output simply stops for a short moment
every 30-60 seconds. Since the digital display of my av-receiver goes out
during that time too I guess that there's no output at all in those moments.
What I consider the most strange is that it's converting the audio to 8bit? I
couldn't find anything about this in the docs and the output certainly
doesn't sound like it's 8bit.
Soundcard is SBLive!
