hi all!
does anybody know what happened to the source/external mic setting.
i use the external mic that came with the player.
i have the line in setting and i use it. But I have to use max gain aswell to hear anything. Its strange! correct me if im wrong, but it should be a fundamental difference between line in and mic.
line should be a sterio connection while mic should be a mono and a feed to power the mic.
im puzzeled.

could anybody enlighten me?

Febs:
There has never been an "external mic" setting in Rockbox.  The original iriver firmware had one, but the only difference was a difference in software gain.  Use the line in setting for recording with a microphone.

Davide-NYC:
Mic Input uses the INTERNAL microphone. (the one on the side of the unit)
It is a stereo signal but either channel is identical. (so really dual mono)

Line Input uses the Line In jack on the top of the player.

The playback volume (for both Line Out and Headphone Jack) is determined by the Volume setting on the WRS (While Recording Screen) and the gain settings (Right and Left independently) are determined by the Gain settings on the WRS.

Maybe you have the gain settings too low?
Maybe your microphone is broken?
Maybe you Line In jack is a bit messed up?

Another possibility is that your AGC is turned on and the Max AGC gain is set way low. This would preclude you from raising the microphone gain higher than the AGC Max gain level.

Please report back.

has the volume control on the recordingscren something to do with the volume of the recording? I thougt it just was a monitor setting so u could listen to the recording while it was recoded at your preferd volume...

Abut the AGC: I have it on voice (fast) , since im recording lectures, and 400ms thats the only two AGC settings I can find. but I cant find the setting that u talked about, the "Max AGC gain" were can I alter it?

Your understanding is correct.  The volume setting controls only the monitoring volume, not the recording gain.
