I love rockbox and have it on several devices. Unfortunately, on my e250 I cannot get the pitch control to work. I can speed up the audio to 200% but it does not stabilize the pitch and my audiobooks sound like the chipmunks are reading them. This works perfectly on other devices but I am unable to get it to work on my sansa. I have done several searches and this issue has not been brought up or was different than the issue I am having. Someone with more knowledge than I please help!!
