It would be good to have this in the handbook (and to see what we can do = to improve it). FreeBSD audio typically works out of the box and it's = great when it does[1], but it can be underdocumented black magic to make = it work when it doesn't. For example, I believe it's possible to tell = pcm that when it receives a stereo stream it should redirect the left = channel to the front and rear left, and the right channel to the front = and rear right, but I haven't yet worked out how to do this - I'd have = thought it was the kind of default that we'd want to have. The use case that PulseAudio was [over]designed to fix was plugging in = USB headphones (or connecting a Bluetooth headset) and having existing = audio streams redirected there. This should be possible with the = existing sound stack, but there are some bits of plumbing missing. We = already do in-kernel mixing and resampling, which are the hard bits. = Duplicating streams and redirecting them are trivial by comparison. David [1] Although I had a slightly embarrassing moment when I spent an hour = hunting for docs to tell me how to configure my media centre box do 5.1 = output and then decided to just try it and found it worked out of the = box.=
