I have recently installed build r18563 and am now experiencing awful sound when playing mp3 files via headphones or Line Out. Sound is very quiet through the left channel but the right only produces an awful noise akin to a drill!
Playback via USB is perfect.
FLAC files are totally unaffected.
I have reverted to an earlier build but the problem persists, although uninstalling Rockbox and using iRiver's firmware resolves the problem.
Any ideas/suggestions?
