WARNINGThe current CVS/daily builds of rockbox have a risk of sometimes skipping 1-2 seconds of a recording (no gap, the data is just missing).
I discovered this myself this morning when listening to a show I recorded last night
It doesn't happen a lot but even once is unacceptable imho.
The bug is being investigated, I hope it can be fixed asap.
A fix for the incorrect samplerate for spdif is up for testing.
The reason for all this is that a major part of the code got rewritten to accomodate different encoders (in the past, only WAV was written, now WAV, wavpack and mp3 are supported). I just wished the process would have been more smooth
