Can you attach a complete test project we can use to reproduce this problem?
I'm using OpenTK not OpenTK-1.0
as it is too much work to change all my code.
I'm switching to OpenTK-1.0 I think it must works, as lots of peeps would have complains if not ;)
OpenTK-1.0 seems a come back to the original OpenTK API, same than GTK and OSX version.
same problem with OpenTK-1.0..
and I can't give my project files, it's a big project solution.
tried with the stable channel
Version: 188.8.131.52 (Business Edition)
Build date: 2013-11-11 16:04:00-0500
the test is easy just call
var actx=new OpenTK.Audio.AudioContext();
and launch it on the simulator in debug mode
I created a sample project, added a reference to OpenTK and added this:
Console.WriteLine (new OpenTK.Audio.AudioContext());
and it works just fine (it prints: "Default Audio Device (handle: 27, device: 26)")
Can you try to create a new project from a template, add your test code and see if that works for you?

I've done it I have the same problem

That sample works fine for me.
It does in fact look like something goes wrong when enumerating audio devices on your machine. Are you running in a VM?
no, it's a mac mini with osx maverick
no, it's a mac mini with OSX maverick.
And all works fine in the simulator with my projects
developed in objective C using Xcode.
but I use a http://www.motu.com/products/motuaudio/ultralite-mk3
as sound card.
but this code was working at summer 2013 with same sound card...
Can you set the MONO_TRACE environment variable to this:
rerun the app, and attach the application output? Here's a screenshot of where/how to add the environment variable: http://screencast.com/t/DCFwpIdQJ0O

I looked at the Xcode.app, there is no Xcode.app/Contents/Developer folder
There should definitively be a /Applications/Xcode.app/Contents/Developer directory. Can you try reinstalling Xcode?
I've done this already last night..
but I think I made a mistake checkin it, the folder is there..
and all the .axbundle are there too
In any case those "Cannot find executable for CFBundle..." messages should definitely not appear.
It looks like other people have also run into the same problem: http://stackoverflow.com/q/18036381/183422 - can you try resetting the simulator as those answers suggest?
but I tell you my simulator works fine will all my xcode (objectiveC) projects, that use this bundles..
I've deleted again the entire xcode.app folder.. and installing it again too. It will change nothing, OpenAL works just fine for Xcode project in objective C ran in the simulator. The problem only appears with Xamarin projects that use OpenAL and being launched in the iOS simulator.
I'm really annoyed to can't work on my Xamarin.iOS projects since more than 4 months, cause of Xamarin and their bugs...
Could you attach (as a file) the complete Application Output as I requested in comment 16 (with the MONO_TRACE environment variable set)? Note that you should get a lot more output than what you pasted in comment 17.

like you said it's a problem with the device enumerations.
I've unplugged my firewire audio card, and it works.
it could be fine if you could just skip audio cards without openAL.
As this I could continue to hear my music and coding ;)
still I can't hear my music and use the emulator same time, cause of this bug.. so no emulator until fixed... :/
Thank you very much for submitting the report and for providing us with all the information. I have an external USB sound card for a pair of Sennheiser headphones that I used to attempt a reproduction on this issue using the latest Xamarin.iOS bits (10.12.0.14). I was unable to replicate the issue using the provided instructions and steps. If you're still encountering this issue after updating to the latest version, please let us know.
Unfortunately, we don't have the device you're experiencing the issue with, but I can attempt a reproduction again with my external sound card (as long as you can confirm that USB connections exhibit the same issue as well). When responding to this report, please include a sample project (even though the code snippet you provided was simple, I want to ensure we're working from the exact same base) as well as exact steps you take.
