First question here!

I have a 13" MacBook Pro with Ubuntu 10.10 and I get every piece of hardware working without problem... but sound input.

My machine can reproduce sound correctly, but I can record nothing. The 13" MacBook pro only has one jack connector for both, input and output.

How can I solve this?

Thanks in advance.

See my answer at Bad sound quality and headphones not working for the steps to troubleshoot the issue and provide more information. This is an issue with sound support in the Linux kernel.

You either need hardware that works with that combo-port or you need an adapter that splits it into one line-in and one line-out port. Bottom line: not an Ubuntu problem.

That's not the point. I only want to send audio and recording, not both send audio and listen through the same jack connector. I can listen what I'm recording through the laptop speakers. – kerunaru Jan 29 '11 at 20:34
You cannot use a combo port with an ordinary line-in jack, only line-out works fine with those ports. An example for such an adapter (note the three rings on the jack) is the SteelSeries Mobile Device Adapter (I guess you'll find cheaper ones on eBay). – htorque Jan 29 '11 at 20:42
Is not there a way to do it through software? On Mac OS X I could switch between use the connector for input or output... – kerunaru Jan 30 '11 at 10:33
Oh, really? I didn't know that it's possible in Mac OS X, sorry. I just haven't found a way to make this work in Ubuntu and Windows 7, so I have assumed that it's a hardware limitation. – htorque Jan 30 '11 at 13:02
No probs. Same here, that's why I asked here. Maybe someone has the solution... :-/ – kerunaru Jan 30 '11 at 17:32
