UI: Fix crash when no audio backends are available

Browse Source 
This commit prevents a crash in, for example, Linux configurations
where PulseAudio is disabled, which leads into 'mod' being 'null',
which in turn leads into a segmentation fault when an ALSA source
is selected.

Closes https://github.com/obsproject/obs-studio/issues/3485
