Sometimes, my H10 stops playing music, and then it can't read files. Like a HDD failure or something like that.
For example, when I try to play a music file, I get a "Can't load codec" message.
When that happens, I'm pulling out the battery and replacing it and then it works.
What can it be a problem of?
P.S. Is there any guitar-tuner plugin for Rockbox using the built-in microphone?
