Hi,

I'm new to the Rockbox software so I hope this issue is commonly reconized and can be solved. So help pls.
I have iPod Mini 2gen 4GB for 4 months now and I was very excited when I found Rockbox on internet - a software which addresses two vital options iPod didn't have - equalizer and crossfeed.

I have installed Rockbox succesfully and enjoyed it very much until I started to tweek with equalizer.

Issue description:
1. If eualizer is enabled and when WPS is viewed Rockboxed iPod plays for 5 to 30 seconds and then it stops for less than second to activate disk (virtual diode), and then palying resumes for next interval (the same length), and so it goes - playback-gap-playback-gap and so on.
2. If I leave WPS and enter any menu - the effect of interruptible play dissapear, when I'm back on WPS - it's back again.
3. If I disable equalizer - everything works fine.

I tried to tweek with some disk buffer sensitive settings (Disk Cache, Anti-Shake Buffer, Directory Buffers) but with no success but some minor changes in the length of the interval betweed succeeding playback gaps.

I should add thad iPod is new and legal, no tweeks applied, device not serviced yet. Rockbox installation done w/o problems.

Is this issue known? Can someone help me with it?

Regards,
Michal Rogowski

This is a performance issue and covered in the FAQ. Turn off the EQ and use a theme without peak meters.

OK, do you say that it's no use in enabling EQ?  >:( Oooops, I installed Rockbox just for that purpse.

Is there any way to fix this problem? Is this possible at all with iPod mini? Is this because the processor power's not sufficient?
I noticed that with EQ enabled but all gains zeroed it works fine.


BTW no mention about this issue  in faq or I'm blind or dull (or both  ;D)

Regards, Michal

From the iPod FAQ

--- Quote ---Playback is glitchy / skips!
Again, it's in early stages. The simplest solution is to choose a WPS without peakmeters, for example iCatcher. Higher bitrate MP3s especially have these problems, as well as higher bitrate AAC files. This is beacause there is still quite a bit of optimization to be done on the iPods. During decoding some files the one core used is at nearly full capacity, which is why you may notice slowness in the menus or adjusting volume. If you have replaygain or equalizer settings enabled, turing them off may improve your playback quality. As well, using a simpler while playing screen, preferably one without images, may also help considerably

bascule, thanks. It seems that I'm dull,  anyway  :o

It doesn't answer my questions, however. In the meantime I tweeked a little, wrote my own simple WPS w/o peakhold meters, turned off anything could load processor, but enabled EQ. At first glance I thought that it's OK, but some more changes in EQ settings (Q and f) led me back to an old issue. Now gaps occour seldom, but still they are. I wonder if someone will cope with this issue in the nearest feature...
