[Openal] HOWTO specify a backend/output at runtime?

[Dirk]

How do I get an array of strings for possible output-devices/backends I
can/could use with alcOpenDevice() ? So If I want to use SDL instead of,
let's say ALSA, how do I find out it is active and how do I know which
string to use with alcOpenDevice()?


Thanks,
Dirk
