Only soft abort when getting k_pch_audio_Section
Overte and according to #65 Sansar hard abort on getting the audio device.
At least in Overte this is no reason to kill the application as it handles an "empty" case and doesn't even have an implementation on linux. https://github.com/overte-org/overte/blob/17b483284d98edbcf715651cea7b7c471dd363cf/plugins/openvr/src/OpenVrDisplayPlugin.cpp#L743-L775
