You have an interesting definition of "great". 1- It doesn't work without an annoyingly complex, extremely badly documented user configuration. To the point that it doesn't work in either an out-of-the-box, updated Fedora Core 3 nor an out-of-the-box gentoo. 2- It doesn't work for programs that do not use the annoyingly complex and horribly documented alsa library, which includes everything that still uses OSS[1]. You call that great? Multiple audio streams is such a basic feature it should work, period. No if, no buts, and no obligatory library. Which doesn't preclude having it in userspace, mind you. But it should never have been the _application_'s responsability. OG. [1] Which is so easier to use for normal programs' audio it's not funny. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
