Re: [Om2008.9] Using Freerunner as a digital audio player
FWIW, the qtopia media player in the testing branch is vastly better than it was. Volume control even works now without causing distortion! From my observations, the audio quality issue has been due to CPU load and not the player itself. Even in fairly recent builds, the poor freerunner was pushing very high loads and causing the media player to mess up it's decoding. Try ensuring that only the media player is taking CPU time when playing music. I am neurotic about good sounding audio, and I love the FR, even with headphones. I was just now comparing it to an iPhone and prefer it. You do need to tweak the mixer settings, however. Some of them are offensive to the ears.

Re: [Om2008.9] Using Freerunner as a digital audio player
The qtopia mediaserver takes ~35% cpu to play my max bitrate VBR-encoded mp3's. I don't have mplayer installed and not /dev/dsp for madplay so I cannot test with those. For average tasks, the UI is still nicely responsive in these latest testing builds. Anytime the load gets to 2, though, you start to get audio cutting out. GTA02 is not a brute. I actually have not tested audio interruption (i.e., incoming call) in a while, but I have never had a problem with it.

As I am too afraid of breaking the openmoko i won't change the capacitor myself...but what could I do? build/buy an external amplifier(will it work fine?) or find a place where they could remplace me the capacitor? I wanted to remplace my old ogg player with the openmoko...because my old ogg player is(pma430): *not powerfull enough to decode all the internet radios(such as mms://) *has a lot of bugs(the port of mplayer is buggy on it,and the default audio player too) *can't be easely programmed to make a usefull(quick and dirty) player...because there is an old qtopia,python hasn't the gtk library,mplayer is buggy etc...so making a player is out of my capacity... So I Thought buying the openmoko that I could also use it as a ogg/radio player...but without headphones...I can't listen to it in the metro... ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
Re: [Om2008.9] Using Freerunner as a digital audio player
Mmmm that's strange because everything sounds good under Debian. But thanks for the hint, I will check my cpu usage. You are right, after a bit of killing : - it sounds good with qtopia media player, and mediaserver eats 45% of CPU in top - it sounds good too with mplayer (frontend here http://www.opkg.org/package_1.html) and it eats only 30% of CPU Xavier. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

The bad quality is caused of that pulseaudio and the openmoko-mediaplayer uses near to 100% cpu time. I converted some mp3 to mono 64kbps, they sound good.And cpu usage is around 60%. Here a little script: #!/bin/bash 400 MHz unable to decode 128 kbps mp3 on the fly??? My 486-66 did it with winamp! I think there might be some problem with latest qtopia's mediaplayer (or sound server). The same files I heard flawlessly on 4.3.3 snapshot, continuosly clicks on 4.4.1.
