I’ve just upgraded my 2GB Sansa Clip to firmware 02.01.35 and now the overall volume level is MUCH lower than before. This is across the board (i.e. FM Radio and mp3s at all EQ settings).
It’s not my headphones or my ears as I get a decent volume when the same headphones are plugged into an iPod. Plus I’ve tried three different pairs of headphones and they are all too quiet at full volume on my Sansa.
My battery is fully recharged and the Sansa Clip is less than a week old.
