 If you want to over-amplify (will crackle if you overdo it == play loud recording with high volume) the audio with the software volume control (eg. I just watched firefly with my Pandora and really couldn't hear it properly with the integrated speakers because it was too quiet recording), modify .asoundrc(add the + line, without the +):

		+	You can change the max_dB to suit yourself, but 12 is a good starting value if you have no idea (it's what the winamp preamp allows by default, some audio card drivers, etc). If it's too loud (crackling) after this, you can also just compensate with the XFCE mixer (or alsamixer from terminal) (the analog volume scroll wont fix this).

	The Pandora has a high quality Digital to Analogue Converter ([[DAC]]). The sound signal from the processor is passed to an analogue amplifier, and at this point a signal from the volume control wheel is applied (so the OS has no visibility of the volume wheel, you have a final physical control over the volume).
