>Does anybody know where to find user manual for version of rockbox running on DX50. I tried to find ti on official rockbox site but failed to find it. I assume that manual for touch screen devices are different than for other devices?
Rockbox has an automated system for building manuals for every player based on firmware settings and keymap, I'll try to build.
>I think you broke something with this. I typically find -22 dB to be a comfortable level both with my Clip and with Rockbox. Today, -22 dB is barely audible. Reverting to yesterday's version brings the -22 dB setting back to -22 dB.
Most probably fixed, that was due to wrong sign when I was combining hw volume with sw balance.

>Also -- and this is a minor thing so don't bust yourself on it -- car adapter mode only half works (2014-03-13). The player pauses when USB power is removed but does not resume when power is restored.
I don't even know yet what is a car adapter mode
>I notice the menus settings/menus are a bit re-arranged? Also on the main screen, the "shutdown" button is erroneously renamed to "Recursively"
That could happen, I will update language files with every build from now.
>Does the lock switch works on your DX50?
Yes. There was a bug - it was broken for cases when spdif or lineout inserted, but now fixed.
