I'm writing you to know if somebody else has the same problem as me.
The thing is that I can't adjust the volume in the "edit track details" tab. I see the "Volume" value (always zero), but there is no way tu adjust it.
Other problem I'm having is that the smart lists dont work in the same way iTunes (sorry) does. For example: in iTunes I can specify "media type", but in gtkpod I can't. In iTunes I can specify a playlist too (in a smart list), but even when the gtkpod shows me the selectlist corresponding to "playlist", no playlist is shown in there.
Mi iPod is a Classic, 120G, and I'm using Ubuntu 11.10.
Please, help!!! It's almost my last step to stop using Windows!!!
