PA buffers better than ALSA, or is supposed to, in any case. Of course, if you're using its ALSA-emulation that's a moot point. AFAICR (haven't had this problem for ages), CPU usage from PA is basically caused by the resampling, which you can just modify to a simpler method if you don't need the higher quality of the default (speex, I believe).
I have been using the ffmpeg resample method because of that, it uses less cpu, or seems to use less cpu here, and with my setup I cannot detect any loss in quality, but hey, it is a laptop and the analog audio path is not stellar so ymmv. -- Mauro Santos
