Ensure sample indices are initialized also with sound disabled

Browse source 
The assertion of #8262 can be reproduced when sound is disabled or failed to be initialized, as the sample indices where not being initialized properly in these cases. It is still necessary to initialized them so sounds can be loaded in the editor also when sound is disabled.

The potential thread-safety issues of the `CSound::AllocSample` function are not yet resolved so the issue remains open.
