Not sure why I'd need/want that, so I used your list of patches and compiled my own a few days ago.

Channel swap is of course optional, not mandatory. It's enabled/disabled in sound settings > channel modes.

Oh, that's awesome. I'll totally use it then. That way if I pick up a pair of IEMs that are more comfortable to wear the wrong way (like looped over the ear instead) I don't have to mess with a cable swap.
Thanks, dfkt.
Edit: By the way, I just installed the new bootloader and r31375 and found that it doesn't pick up any radio signals anymore at all. I'll have to revert back to previous versions to see what the culprit might be, because there were at least 20-25 stations before this. Must be a new bug somewhere. Anyone else experience this?
Edit 2: This is resolved and it was my own fault. I didn't have the headphones connected, so naturally the signal was extremely weakened.
TexasRockbox:
I notice that with the clip zip white letters and graphics tend to take on a reddish tint at lower brightness levels (0-3).
I have two 8G clip zip -- one bought from Radio Shack USA which seems to have less of the problem, the other bought from Costco (slightly improved casing) which seems to exhibit the problem more. Could this situation be due to the two known OLED display manufacturers for this player?
Both players have the same Rockbox firmware.
Where in the Rockbox code should I look to adjust contrast, saturation, hue, etc. (if possible) for the clip zip?
bertrik:
Yes, it could very well be possible that the reddishness at low brightness differs between the two known OLED types.
Rockbox currently uses the same brightness curve as the original firmware (at least that's the intention). This is basically a simple linear curve, for each of the three R,G,B components. Possibly the B and R components are swapped for the brightness calculation, this is very hard to determine for the Visionox display I personally have, but should be easier to determine for the Wisechip type of display.
In principle, rockbox could implement a more advanced brightness curve, simply by creating a table with R,G,B intensities for each brightness level. The only concern then is whether this curve is reasonably the same for each individual display of a certain type, but it would probably be an improvement over the current situation anyway.
saratoga:
We now have working install directions on the SansaAMS wiki page (see first post of this thread). Alternatively you can also use one of the unofficial bootloaders on the ABI forums. As soon as a new release of rbutil comes out, that method will also work.

Or use an svn build of Rockbox Utility (yes, still svn builds -- there are no builds from git yet). I've uploaded a build just a few days before the switch to git, so it's still rather current. See my signature for the link.
