I tried out polypaudio a couple of days ago because Ubuntu is aparently switching to it. In general, it seems like a great concept, and I’ve heard great things about it, but I have this one problem: it dies with an assertion on ppc. It only seems to happen on PPC (x86 and amd64 both work fine) and I can’t seem to find a bug reporting tool for the project, so I don’t know where to file bugs upstream. I’d be more than happy to try this sound server out (anything is better than ESD :), but I’m afraid I can’t. Please, if this is going to be a replacement for ESD, it has to be programmed with cross-platform use in mind.
