How do I get past the return statement in the Control Register?

Area of Cosmos - What area of Cosmos are we dealing with?

T<> Lists…

Expected Behaviour - What do you think that should happen?

It should take the first integer stored and use it (sound card)

Actual Behaviour - What unexpectedly happens?

When I try to use a snipet like this: var aVariable1 = ANamespace.Aclass.AstaticListFunction(); var xVariable2 = xVariable1[0]; I get an exception saying: Parameter Name: <Enum.ToString> Not implemented...

Reproduction - How did you get this error to appear?

When I added it into my code for vital functioning purposes, it throws an exception in the VM as a runtime error but not on the build or debug output.

Version - Were you using the User Kit or Dev Kit? And what User Kit version or Dev Kit commit (Cosmos, IL2CPU, X#)?

The latest UserKit 20200708.

I got it to work. First I changed the MemoryAddressSpace to IOAddressSpace. And inside the GenericSoundCard constructor. Then I changed the mem = deviceP.GetAddressSpace(1) as Cosmos.Kernel.MemoryAddressSpace;

to mem = deviceP.GetAddressSpace(0) as Cosmos.Kernel.IOAddressSpace;

Here is the project with these changes. Also, I cleaned up some code in the project. CosmosSpeakerTest.Modifed-V2.zip

You need to implement the driver for some more advanced speaker/sound card. As @valentinbreiz stated, only PC Speaker is currently implemented so there is no way to play wav files. If you for example finish the ES1370 driver, you could then play wav files.
