Even though I agree ALC_DEVICE_SPECIFIER should return the actual device 
name(s) with a separate enumeration for listing drivers, that's not how 
implementations work. Before OpenAL Soft was even thought of, Creative's 
wrapper was already returning the basic "Generic Software" and "Generic 
Hardware" driver names through ALC_DEVICE_SPECIFIER, with the individual 
device names coming from either device-specific drivers or through 

<https://icculus.org/alextreg/wiki/ALC_ENUMERATE_ALL_EXT> was made 
specifically to be able to enumerate the individual devices instead of 
the driver names. If I changed this for OpenAL Soft, making 
ALC_DEVICE_SPECIFIER return the full name, it would create an 
inconsistency with other implementations.
