Using OpenAL-Soft in Ubuntu fails to return device

Question

I'm new to audio programming in Ubuntu 20.04 and was looking at open source audio libraries and found OpenAL-Soft. I'm following this tutorial online https://www.youtube.com/watch?v=kWQM1iQ1W0E&ab_channel=Code%2CTech%2CandTutorials

The basic code used is

ALCdevice* p_ALCDevice = alcOpenDevice( nullptr ); //nullptr = gets default device
    if( !p_ALCDevice )
        throw( "failed to get sound device" );

When I do this it returns

[ALSOFT] (WW) Failed to open playback device: Could not open /dev/dsp: No 
such file or directory
[ALSOFT] (WW) Error generated on device (nil), code 0xa004
terminate called after throwing an instance of 'char const*'
Aborted (core dumped)

When using

const ALCchar * devices = alcGetString( NULL, ALC_DEVICE_SPECIFIER );

and

printf( "%s", devices );

it outputs

OpenAL Soft

not even sure what this output means and what it has to do with my audio devices. Anyone know whats going on?
