Good news!
What exactly does the line "Greatly improved pitch accuracy on Sansa e200v2, Fuze, Clip and Clip+" mean?
Lasse

The OF for at least Fuze and Clip has pitch issues. Varies with model, but my V1 clip played 0.7% fast/sharp.

3.7 enables a special PLL clock providing an optimal ratio for 44.1kHz PCM playback on ASMv2 devices (Fuzev2, Clipv2, Clip+). AFAIK all those devices played 1.1% flat with rockbox, with 3.7 the pitch error is reduced to 0.04% (which is more precise than the original firmware).

Edit: here's a measurement showing the pitch error on Clip+ with old/new rockbox and OF
