@cooperpwc : I have also this issue, the Q curve setting of the LS band resets itself to 0.0 after a shutdown. There are some changes quite recently into EQ handling code, and the patch needs to be sync'ed with the latest source. I tried to make a build a month ago with only the "10-band eq"...

Once it is compiled (ie packaged into a zip file and ready to use), you cannot unpatch the firmware. Must revert the changes on the concerned files first, and recompile (&repackage) rockbox. I also attempted to make a build to suit my needs. It has the same patchset minus "volume cap at +6dB"...

Quote: Have it running since one month on an EU-capped iPod (bought in France) . And yes it is volume uncapped after Rockboxing.
