OpenAL Soft 40964 in alcOpenDevice: AL_INVALID_OPERATION

Question

When running my audio application, ported from Windows, on Ubuntu Virtualbox, it reports the following:

Devices found:
OpenAL Soft

OpenAL Soft 40964 in alcOpenDevice: AL_INVALID_OPERATION

The line it runs on:

ALCdevice device = alcOpenDevice( NULL ); // Also tried "OpenAL Soft"

Ubuntu audio is working properly. What am I missing?

CMakeLists:

target_link_libraries( ${PROJECT_NAME}
    "myengine"
    "openal"
)

I installed libopenal1 on the target VM

Apparently, the alGetError() will return this error before a context is created. Starting from alcMakeContextCurrent() I can use this function to check for errors.

It now plays audio!

So for alcOpenDevice() and alcCreateContext() I had to comment out the alGetError() error checking. Though I could still check whether the device was opened successfully using if( !device )
