Trying to go 100% Linux
 
I recently installed Ubuntu 11.04 on my iMac dual boot. I spend about 80% of my time in Ubuntu and the rest (20%) on the Mac. That 20% really irks me because I would love to go 100% Linux but a couple of things really bother me that I still can't do in Ubuntu on my iMac. The first thing is that I can't use the internal web cam that comes with the iMac. I read the help page on how to get it to work but have no luck so far . The second and most important thing that really bugs me is that I am unable to record anything from Sound In. I am a radio host so I need this functionality to record my radio shows. On the Mac side no problem. Works fine. When I boot into Ubuntu, there is no sound at all coming through Sound In. I have a radio attached to my iMac that I use to record my radio shows. I would love to get this Sound In problem resolved, and then, once these two issues are resolved, there is a good chance I will switch 100% to Linux. Until then I will just have to make due with that 20%.

Hi and welcome to lq!
It might help to post the technical specs for you webcam and your sound card if you're expecting help. Most people don't know these things off the top of their heads.
ciao,

Code:

lspci
is a good start.
Code:

lsusb
is good if anything is plugged in via a usb port. Be sure it is plugged in when you run this.
That should get you a start at least when you post that.

Ok. If I understand you. You have no sound at all, incoming or outgoing. If this correct then you need to configure your sound system. I googled using linux N10/ICH 7 audio as keywords and got a fair number of hits. You can browse through that info and decide what is relevant for you. An easy solution would be to but a headset with a microphone and plug it into a usb port. Is there a problem doing that?

For your webcam I googled Built-in iSight [Micron]. There are many hits. On that seemed relevant is this one: http://handyfloss.net/2008.07/making...ork-in-ubuntu/.
You made the following comment:

Remarks like these are unhelpful because you don't give any details. What did you try? How did the system react? and so on. If you're having a problem (and if you have problems with what I or anyone else suggests) then you need to describe in detail what the problem is.

You can also get a webcam that plugs into the usb port. I have a desktop with no built-in webcam and that's what I use. It works fine and "out of the box". I just plug it in and it works. You can get one for under 20€ so they're not too expensive.

I can listen to music no problem with that. The problem is sound in. When I have the radio that is connected to my iMac playing, if I go to my sound preferences and select input, I should see sound levels on the bar. I don't see anything. On the mac side no problem . This is what my problem is. Other than that, I can listen to music edit music no problem.

Have you tried looking at the alsamixer or whatever pulse uses as a mixer. (if you're using alsa/pulse - you don't say). They should indicate your soundcard and what properties have been enabled. Sometimes a given setting is muted by default. You might want to look at and post the output of
Code:

aplay -l
as well.

Thanks. I will post back the output. As far as the iSight. I tried what was on the Ubuntu help page regarding the iMac and the iSight camera. I'm still plugging away at it. :)

On a sidenote. I notice that you are from Gorizia. My wife's family is from Civedale. I love visiting that area of Italy!!

I guess you mean Cividale. That's my GF's bank: Banca di Cividale. If we go to Udine (I had some heart surgery done there earlier this year so it know it well) we can get a non-Trenitalia train to Cividale. It's supposed to be quite beautiful. Maybe we'll get out there this autumn (we don't have a macchina so it must be by train).
Say "salve" to your wife's family for me. :)

At this point I would try playing with alsamixer. Hit F4 to see the Capture settings. Make sure the Capture settings (a) exist and (b) are not set to zero.
