[openal] how to uninstall OpenAL Soft on Windows 10

[Carlos Nazareno]

Hi. I recently bought  a physical soundblaster X-Fi card that supports
EAX and OpenAL in hardware.

I wish to safely uninstall OpenAL Soft (version 1.21.1 on Windows 10)
now and use the creative hardware OpenAL as I notice reverb effects,
etc are not as crispy as when I had my Audigy in games.

So far I have not had luck finding instructions via search engine on
how to uninstall OpenAL Soft, and some games are still listing OpenAL
Soft as my sound provider.

Help appreciated.

Regards,
