if phonon-gstreamer dropped support for ALSA and OSS, and forced everyone to use pulseaudio

Which is actually a good suggestion - problem with Linux audio is that there are too many connections in the graph of audio stack components.

But pulseaudio is using ALSA anyway, so where is gain?

+Daniel Horecki Sane API, less than hundred different combinations to test, friendly upstream...
And PA gives more than what's supported in ALSA (Bluetooth audio comes to mind).

Unification. Right now we can have different applications accessing audio hardware in different ways - some directly access drivers via ALSA or OSS, others use Pulseaudio, or JACK, or whatever.

+Tomasz Torcz On the other hand, is there any way to marry PulseAudio with JACK in a usable way?

No, they serve different purposes. That's why PA yields device when Jack asks for it.

Hmm, alternatively: https://docs.fedoraproject.org/en-US/Fedora/14/html/Musicians_Guide/sect-Musicians_Guide-Integrating_PulseAudio_with_JACK.html

I wonder what was wrong with reading how JACK works and simply reusing same method in PulseAudio to achieve low and constant delays.

As I see, Jack generates fuckloads of interrupts, waking CPU and draining battery. PA in optimal cases let CPU sleep for few seconds between wakeups.
