Call it what you like, that's what it's supposed to be doing without headphones plugged in: filter out or otherwise limit certain frequencies that would damage the speaker. I don't know the details but e.g. Arnim/Pupkin has investigated this quite a lot and was the one i heard describing it.

There does seem to be a lot of PA overhead in general and it would be good to have some answers and options. Coming from a crappier phone music player, N900 audio sounds great to me, but i'm sure it could be better.

I leave it playing, then I either use load-applet or the button in the interface; the volume button works 100% when the app is backgrounded.

You should reinstall, a new version came out yesterday.

I really can't agree with you on the soundquality but this is a good topic to discuss about mediaplayers smooth playback which is part of good soundquality.

Pulse Audio is pretty heavy in general even without adding additional processing to protect the speakers.

I wouldn't mind it so bad myself if we could actually reap the primary benefits of a Pulse Audio system: http://talk.maemo.org/showthread.php?t=36936

Not having the overhead issue on my N900 through 3.5 jack. 192kb files range from 12 to 14% cpu when adding the two processes up.

Stock player.

Re: Lack of audio quality on the N900 and useless overhead
 
the main thing that annoys me about the additional background processes is that when im browsing the internet it stutters quite often. i really dislike this because the thought of having a powerful processor in my phone is marred because my old tmobile wing (@200 mhz) did similar but not as bad. i hope they resolve this issue soon.

Maybe somebody could write a script to give the mediaplayer higher priority untill this gets fixed?

MPlayer can bypass pulse. It's probably not a good idea to do this, as it will block everything else that wants to play sound.

mplayer -ao alsa:device=hw=0.0 file.mp3
