dumdasme, thanks for confirming xman954's new version of the 4920 audio exploit works with the UberDash on a 5838! (Although expecting it would, technically, it's great to know for certain that it really does.)
If you have enough space left, you could add the 'settings3' and 'settings_panel' XIP's (just for shits'n'giggles) to enable its [Settings]->[System Info.] ... hardly anyone has ever seen it display K:5838 and D:4920 before.
