The ALSA userland emulation in PulseAudio is supposed to faithfully emulate the behavior of the ALSA kernel ABI... except when it doesn't, then it's not a bug but rather a feature. :-) > I also agree that the open/close of the alsa device is the only way to > control exclusion. I was also a proponent that we should have fairly coarse locking done at open/close for the various device nodes (ALSA/V4L/DVB). The challenge here is that we have a large installed based of existing applications that rely on kernel behavior that isn't formally specified in any specification. Hence we're forced to try to come up with a solution that minimizes the risk of ABI breakage. If we were doing this from scratch then we could lay down some hard/fast rules about things apps aren't supposed to do and how apps are supposed to respond to those exception cases. Unfortunately we don't have that luxury here. Devin -- Devin J.
