Gigabeat S: Turn off hardware effects (tone and 3d) when doing digital loopback for FM recording otherwise the signal and levels are poorly represented in monitoring (can't just do ADC->DAC for general FM and get voice too). Some tweaking to input setup to improve gain a tiny bit. A little bit quieter startup too.
