Hi 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.
