Well, "got rid" sounds a bit pathetic. We are no longer using it :)

No problems. Using alsa dmix now and despite Lennart's constant railing on 
dmix, on GTA01, I can play two mp3 (via GStreamer) without any dropouts, 
whereas with pulseaudio I hardly managed to get one without dropouts.

None, sorry :)

Well, pulseaudio is great. Honestly, I love the concept, that's why I pushed 
it in to Openmoko in the first place. But alas, the current state is way 
unusable on our slow systems. Perhaps this will improve with the new branch, 
lets see. Until then, it's alsa dmix for me.

Absolutely. GStreamer is great and will be a vital part of the Openmoko

If you want to maximize performance, go alsa. If you want to maximize reusing, 
go GStreamer.
