When does 0x1cd8 trigger? During playback or some other time?

I've updated the OP (it took a while to reproduce, it's at 30026264). The crash occurs on track change/skip only.
EDIT: Revision was r25705

This is my first post.
Can I first say kudos to all of you who are working on getting a rockbox build working for the Fuze v2. I have for the first time tried the build (and rockbox) on my Fuze 2 and see great potential. I used the daily build from yesterday (25 April) and a pre-patched firmware .31 version from one of the developers here which was posted on the Sansa forum. It worked!
Of course there are lots of bugs but no complaints. Here are some I wanted to report:
1) Volume - the volume will often lock and then it cannot be changed with the scroll wheel or the menu (sometimes the menu will work.
2) Screen flicker - noted already
3) Cue files do not work yet
4) Crashes when flicking through EQ presets (not always)
5) Crashes always when you scroll through some of the higher (or minus that should be) DB values for precut - mine crashes always when scrolling around -4.5/5 DB
6) the Volume seems uncomfortably loud on my in-ear headphones but perfect for my full size headphones. Is this normal (tried the precut but it crashes)
7) Will sound quality improve in later builds? It is good but it lacks, what to me is the full bodied sound of the current .31 firmware of the Sansa when listening to flac files. I am a believer in not using EQ as my headphones sound great with no EQ on the sansa and the fuze sounds excellent through my stereo amp with no EQ so I am thinking of sound quality "out of the box" (of course with the wonderful features of crossfeed and dithering!!! - brilliant)
8) To get round the non-saving issue for settings, I wrote a fixed.cfg file (note the manual has a value of 60 for volume!!!! I think this needs to be -60 to stop your brains being blown out ;-). In the fixed cfg file I can't seem to successfully be able to set Crossfeed or Dithering but setting volume, bass and treble works fine (as does setting a new theme, which is great because I don't have to change the theme on every boot ;-) due to lack of writing support).
Once again, a big thank you. I will donate something to the fund in due course.
Happy also to test daily builds and feed back.
Cris

I added ridiculously long delays after switching CCU_IO in button-fuzev2.c without any visible effect on screen.
EDIT: a delay *before* any operation at the start of the function fixes the glitches
EDIT2: fixed in svn

I read on the sansa forums a while ago about DIY "line out". They have figured out a pin configuration for what people think might be line-out, except you can actually decrease the volume, but not by very much. This sounds like our problem here. Perhaps we are experiencing this, and are actually using the wrong pins (sorry, don't know if that's the right technical word :P) for audio, ie (some sort of) line-out instead of headphone out?

cris' post triggered this thought, since he was saying that the audio had a different feel to it. I figured using rockbox to decode flacs shouldn't really affect audio quality.

From the forum thread:
--- Quote ---The volume needs to be at about 50% or greater (doesn't really increase much from that point on)
--- End quote ---
This is different from rockbox:
On rockbox, the real volume is completely unaffected by settings the low 50% of the volume range, but still can go quite high.
With the line out cable, the real volume is affected (although only a bit) by the up 50% of the volume range.
I didn't read the whole thread as I'm not sure if it's related to the volume problem.
EDIT: fixed in r25732
By the way AMS didn't answer to my request of the as3543 datasheet :(
About the sound quality I'm completely unconvinced, it sounds perfectly fine to me, although I'm admittedly not an audiophile at all.
I will trust you only if you can back your claim of different sound quality with computer-made analysis of the output (with lossless source and good analogue recording equipment I think)
