Fixed by updating to Experimental 2.9.14. Not sure if clearing settings had anything to do with it.Before I start, I have Rockbox Experimental 2.7 060610-0319 with v1.29k, bootloader 5.
I use the standard, non-LCD remote that came with my H320. Sometimes, all the buttons work perfectly. Other times, none of the buttons work. As in, you press the button, and nothing happens. It may last for a minute, or for a few minutes.
I have found
this on MisticRiver, but it must be old enough to not have a settinigs menu for General -> Display -> Remote LCD Settings and then Remote type.
I have noted that the WPS sort of 'freezes' and the time elapsed and remaining stays still, and the progress bar is frozen. However the music continues to play. To make it work again, I need to either fast forward, or skip the song, which is annoying.
I have also noted that it most often occurs when I set a sleep timer. I set it to 20 minutes, and hit NAVI. Then I hit fast rewind (or left or the button that is like <<) to exit the menus. This is when it freezes. If I hit PLAY to exit the menu, then it works.
Is this a known issue? Can something be done about it?
