I get a sharp metallic sound from some units

K'nah mean?

I guess I'll just deal with it

I'm sorry. Bovi is currently temporarily absent and he is basically the One True Bughunter/Tech Supporter we have. Anyway you seem to have hit a fairly “unique” problem: I certainly never encountered it. The only possible cause I can think of is your audio card heating up too much; if that is the case, shut down immediately to let it cool down & if possible open your PC case and clean it out (in particular remove dust around the vents/edges because that dust obstructs air flow and thus cooling).

Sometimes it happens that if you select (and move) multiple units, they will respond with a sound like a Star Wars laser cannon. Maybe that is the thing you encountered. It is harmless, though, and probably a vanilla issue.

In previous versions of EB, some Roman units also gave funny responses. For example, a unit in control of a ram would say "Aries! a-a", the last two vocals not belonging there, of course. This has been fixed in 1.2, though.

That's all I can think of off the top of my head.

Just in case you're still around...

I don't recall any such problems from anybody else. I've certainly never encountered it. If you happen to have other hardware (such as another speaker set, another sound card you happen to have lying around or access to another computer), you could try to play a couple battles with that to see if it's something wrong with what you have.

You may have some success with upgrading or downgrading your sound drivers, if possible.

I'd also try to run with the volume set really really low in the in-game sound options (as in, that you can only just hear anything out of your speakers). Perhaps it's not really a game sound after all, but some Windows warning sound when it's trying to do something related to playing the sounds. If it still comes out in the same volume as before, it's a sign that it's not played directly in the game (while the opposite is true if it comes out low).
