Hello,
A friend of mine has the Toshiba Satellite Pro A10 laptop.
It appears to only have a Microphone In. He has been told in a store that it might be possible that it is a double-function input jack, and can be switched to Line-In mode by software, I guess through some switch in the driver control panel, or something like that.
Anybody can confirm or deny this? I have not been able to find any definitive information about this.
