Yeh ! I just retried the 30th Oct build to be precise. Here's what I did :
I've got a playlist of around 350 files - replaygain-ed using foobar 2000
Using loader.bin 2.5 svn build 1407, boot apple-os, rockbox, diskuse, sleep
After loading the build : All this done in proper steps.....
I set the crossfade to mix, replaygain to track, always
No problems with crossfade, works absolutely fine.
Then I, use my own wps,
Still, No problems with crossfade.
Now, I change pitch, to 103
The crossfade is now punctuated with some ugly gaps, still continues playing......if further continued..... rockbox hangs on the next crossfaded track or comes up with an error screen 000.. something
My older build still works absolutely fine, pitch, wps, everything.
So I'm pretty much sure, no absolutely sure, it's something to do with the recent builds, maybe from 20th oct onwards.
