Re: PulseAudio and Phonon?

Forgive me for not understanding, but does Phonon actually use the backend (xine, gstreamer etc.) only for decoding and then bring the sound back in and output it to the final destination (e.g. alsa)? Or does it let the backend do the actual sound output too? It was my understanding that the latter was the case.
If this was provided then surely Pulse adds a lot to the table? Using a Pulse as the final output device would allow for easy hotplugging of audio devices and seamless output. With pulse you could easily start playing a tune in Amarok and have it come out your laptop's speakers, plug in a USB soundcard and then move the playing stream across to it. No need to stop the music and reconfigure things and play it again? Perhaps phonon can do this without pulse (e.g. it has it's own callback based API) and if so then I guess it doesn't add too much other than network device transparency, simultaneous output to all your local sound devices and simultaneous output to all your network sounds devices... which although very cool, it not of interest to most average joe users. |
