What could be going on?
Thanks!I'll try a bench with modified audioset2 and audioset3 to see if it changes anything. no change

You have dumped CGU registers already, now the only difference I can think of is in GPIO registers ? Can you dump and GPIO_DIR (+0x400) and GPIO_DATA (+0x0) ?

Oh well I remember some code which put SDRAM in self-refresh mode, and most of the audio codecs are loaded in IRAM, so the SDRAM could be disabled (I don't know if this can account for high power usage)The datasheet for the SDRAM chip (linked from wiki SansaC200v2) has current values page 4, but i'm not sure which one apply (I suppose the correct value is weighted from all of them)In OF, 0x301C enters self refresh mode (next function leaves the mode), parent 0x1CD8 is called multiple times (I have not identified callers though)
You wrote 7 digits but the correct number has 8, can you post the exact number, and the revision you were using ?
It's pretty clear that the current delays needed for switching to "button mode" (by setting the undocumented CGU_IO bit 12) are not high enough to work in boosted mode.
I have something regarding the volume on Fuzev2 (the fact that you can't decrease it below -39dB). 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 ) for audio, ie (some sort of) line-out instead of headphone out? Found it: http://forums.sandisk.com/sansa/board/message?board.id=sansafuse&thread.id=7792&view=by_date_ascending&page=1cris' 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.
The volume needs to be at about 50% or greater (doesn't really increase much from that point on)

However, I'm finding now that during playback (q8 oggs), I get a lot of skipping, it just sounds a bit dodgy now...
I got a crash while switching tracks (not sure if it's related):Code: [Select]Prefetch abortat A742D41CFSR 0x1(domain 0, fault 1)EDIT: Getting a lot of crashes without error reports during playback. Can barely play a few songs before a crash...
Also, I've noticed that using the hold switch now takes a while to take effect.
if you scroll through a long playlist quickly, you can sometimes suddenly jump straight to the end
