Anyway, I just wanted to say that OC to 900 MHz helps none. It's not a matter of power.

If anything mine seems worse now that it goes to 810 MHz. I'd agree with that statement.

It was supposed to be tongue-in-cheek. I meant, that describes a heapload of bugs in bugzilla.

Re: Stuttering audio when multitasking?

If you want to see proper stuttering of the media player, try it with a bluetooth headset!

It's absolutely ridiculous, CPU usage can go up to 60% with combined pulseaudio+mediaplayer and it drops like crazy.

If you add to that the fact that playing mp3's is offloaded to the DSP that gives you an idea of how many resources it takes.

Using pulseaudio on such a low power device was a bad idea, and it shows, the device barely cope with it hence the stuttering.

Pulseaudio was such a pain in Ubuntu as well. At least until very recently. It has improved a lot in Lucid. To be honest, Someone from Pulseaudio actually blamed Ubuntu for poor implementation.
So, Nokia should take the blame:D

If you define phone as it makes and receives phone calls then yes. If your expecting features like groupable contacts than no.

Really? That's the only way I listen to audio on my N900, and it's pretty good. (Usually with a stereo BT headset!)

If you're the type to say "Hm... Why is this not working?" and look for an answer and type in a few things to fix it, yes. If you're the type to say "Dump Phone! I hate you for not working!" and smash it against a rock to try to "fix" it, no.

Careful... the UI is not the OS. This is unix/linux, the UI is a process, just like anything else, and is not part of the OS at all. You can change the priority of the UI just like you can with the audio process or anything else. (Though I don't recommend doing so.)

To be fair, it is talking to lots of things, between caching images on the file system, maybe pulling tiles over the network, checking the GPS, updating the UI... That's pretty intense.

Personally I have setup a script to launch/nice Mappero when it starts so it has a lower (if not the lowest) priority. So sometimes it pauses (usually just before a turn which it tells me of as I pass it), but the system as a whole can keep up. :)

woody14619, mine sharing the script? I'm guessing it nices the process.

Sure. I just un-linked /usr/bin/maemo-mapper (which is a link to the executable in the opt area) and made it this script:

Code:

#!/bin/sh

#

/usr/bin/nice -n 15 /opt/maemo/usr/bin/maemo-mapper
