2.0  Technical stuff.

[Disclaimer: Kaldar and myself only have PCs so there's not lot of
technical help for the PSX here. I don't think this is much of a problem
anyway as I've been told that even a finite number of monkeys typing
away on a finite number of typewriters can produce software for the
games consoles.... -- snark^]

Basic rule No.1 for any technical problems: Get the latest device
drivers from thy manufacturer.

Every soundcard, graphics card, etc., is only able to work with your
machine via a particular program known as a device driver. If you're
experiencing trouble with the sound and/or vision in TR then I suggest
updating your machine's drivers as your first port of call.  Download
the latest drivers from the manufacturer's website (the URL will be
listed in the documentation somewhere) and also grab the latest DirectX
version from Micro$loth as well.  The newer the driver the better it'll
work (usually).

If you continue to have problems after this, then read on...
