DetailsAccording to my memory (and this wiki page http://www.rockbox.org/twiki/bin/view/Main/IriverRecording) the gain ranges for internal mic went from 0 dB to 30 dB and the line in gain range was from 0 dB to 28 dB.
Currently the internal mic gain range is 0 to 52.5 dB and the line in gain range is 0 dB to 48 dB. These gain ranges are not sane. :-) |
This task depends upon

Hey. I missed you in IRC asking about this. I don't know when this problem cropped but it have been when some info in sound.c was moved to the audio driver. I've no idea other than that possiblity.
- analog, line-in: 0 - 24
- analog, int-mic: 0 - 30
- decimator: -63.5 - 24
which gives ranges:
line-in: -63.5 - 48
int-mic: -63.5 - 54
anything wrong with this (I'll now go and check the code against the above figures)
