I cannot get any audio to play when I play any videos now. I had a crash and now when I try to play any videos in either Zoom Player or Media Player it cannot play any sound. In Zoom Player the audio section is greyed out under 'filters' when you right click the video.

I looked in Graphedit and pulled some vids across and Graphedit gives the error that the audio is in an unsupported format despite installing/uninstalling/reinstalling various codec packs like Matroska pack and k-lite codec pack. In Graphedit after I get that error message the AVI splitter does not show the audio only the pin out for that audio. If you try to attach to another filter like the MPEG1 audio filter for instance it will connect. However I don't know what it is I am supposed to connect that to to try and render the audio to the soundcard output.

It's the audio codec portion is broken in windows somehow (I think) as the codecs that are installed and registered appear not to be being seen or used by any windows type player (Excepting Media Player Classic which does it's own filter thing anyhow but I want windows fixed so that any player works like it did before).

Any ideas on what the registry entry is that could be broken?

Win XP Pro SP1
M-Audio Revolution (I get sound out of it just fine just not from any windows players that pull the audio codec info directly from windows).

BTW Doom9's forum is down otherwise I'd be asking there I guess

EDIT: Nevermind. Fixed it. Was a broken DirectX. Reinstalled DX9C and all is well.

Dammit! It's come back to haunt me!

OK you know I said I installed DirectX 9C and it seemed to fix it? Well I installed SP2 and it's come back (Note: It was doing it in SP1 too so it's not a direct fault of SP2).

I can't reinstall DirectX 9C either since that is part of SP2.

It's something fubar in the registry methinks of course. But what?

I tried the DirectX render test of an AVI file in GSPOT and it says "Render: Partial Failure" on audio but gives no clue as to what causes it to fail. It says audio codecs are registered fine. But the audio rendering from any AVI file is broken!
