Try searching for "file audio output":

The following words in your search query were ignored: file audio output.
You must specify at least one word to search for. Each word must consist of at least 3 characters and must not contain more than 14 characters excluding wildcards.

Also, why doesn't that smilie show up? It works elsewhere:

I disactivated the option. But It doesn't seem to work.

I disactivated the option. But It doesn't seem to work.

You'd need to recreate the whole search index for it to work. And this is more likely to be a bug (since the query is obviously made of 1 or more words of 1 or more characters)

hmmm no, I think the phpBB think audio is a common term.

Try Google with "site:http://forum.videolan.org/ file audio output" instead
