Hi,
I have bought an adapter with a 4-segment jack, as advised in:
http://en.community.dell.com/support-forums/laptop/f/3517/t/19485196.aspx
It works well when I plug in an external microphone through the adapter.
However, it does not work when I plug in a mini-jack-to-mini-jack cable throught it.
One end of the cable is plugged in to the adapter, the other end is plugged in to a pre-amp that I plug in my guitar to.
In such setting, the laptop's built-in mic is still active and the sound from the pre-amp is not recorded via line-in.
So, to make things clearer, this works:
external microphone -> adapter -> laptop mini-jack socket
and this does not:
guitar -> pre-amp -> adapter -> laptop mini-jack socket
The pre-amp can be connected using it's "Main out R" or "Main out L" channels or the "Phones out" channel.
Neither of them work.
I guess the question boils down to:
How can I connect and record any line-in input on this laptop?
Cheers,
Radek
