Sansa Fuze v1 Playback problems above build 27996
orbidia:
If a developer wants to make a build with any modifications, I would happily test it so we can figure out what's happening.
I'm still trying the modified r28711M build and its working great after a few hours of use.
manequin:
I have reverted all my changes and commented out this line. Unfortunately it doesn't solve problem.
Build is available here:

orbidia:
Confirmed.
The build with the single line commented out does not work right.
The sound is terrible though. One thing I notice is that the sound on FLAC is unplayable but with MP3s it sort of plays garbled.
Does playing Flac files take more CPU power/memory than playing MP3s?
More testing - everything acts the same. When I fast forward/rewind, there seems to be a bit less "crazy random numbers" in the status "played/remaining time" fields.
What procedure is possible to narrow down what the problem code is?
We seem to have narrowed down the bad code change between r27996 and r28000. I think it would be beneficial to narrow down exactly what the very last stable version before there was a problem.
So if r28000 was stable and r28001 (tested to be bad) was totally unusable, then the differences between those builds are where the problem exists. I don't have r27997, r27998, r27999, r28000 or r28001. But I remember testing r28001 and I know it was bad so I deleted it hoping the next day it would be fixed...
Manequin, can you post the official r28000 and r28001 build so I can test that and be sure that was the problem jump?
How much changed from r28000 to r28001? If we narrow this down to a single build, we should be able to work out the exact problem.
manequin:
I have already tested revisions from 27995 to 28001. I couldn't make a patch without it ;). In 27999 everything was ok, 28000 was first build that stopped working properly on my hardware. If someone wants to check this on his own hardware, builds from unpached source are available here:

If you go into the debug menu and turn up the boost counter to 1 so that the CPU is always boosted, do it solve the problem without needing to patch anything?
