Simulated battlefields are much better than the real thing: your gun won’t jam, running for your life just means holding “shift+W” and there’s the minor advantage that being shot in the gut doesn’t propel you into a world of terminal and unbearable pain.  But just like in real life, bad communications can get you killed.

Whether you’re exploring a new deadspace complex or flanking counter-terrorists in dust, the last thing you want is for an urgent warning to turn into a “KKK-CHHHH-SCREEEEEEE“, drilling into your ear and distracting you in your (last) vital moments.  Here we look at some common communications problems.

The key here is gain - your room might not be as quiet as you think it is, and with the amplification set too high every whisper of air in the room will become a wailing wall of anti-ear audio.

Especially if you’ve splurged on a high quality headset, the headphones might be insulating you from background noise that you can’t hear but your mic picks up just fine.  The human brain quickly learns to screen out a constant background, but your computer will faithfully transmit every over-amplified bit.  Get into “Setup”, click the “Voice” tab and turn down the amplification.  Use the test function to check yourself things yourself before inflicting earache on anyone else.

The odds are that you’re using something low quality.  The chief suspect is your microphone - if you picked up a $0.99 mic at the “fell off the back of a broken truck” clearance store, don’t be surprised if it transmits sound slightly less faithfully than an adulterous deaf-mute.  After that it could be your codecs: choosing too high a compression level will certainly save your bandwidth, but if you go too far you  could save even more by not talking at all as you’ll transmit the same amount of intelligible speech.  Go into “Setup > Voice” and check your codec settings.

Make sure you haven’t bottomed out your sound quality in the hopes of avoiding lagging.  Sometimes you’ll be forced to low fidelity by the limitations of the ventrilo server, in which case it’s time to go elsewhere or set up your own.

This problem has two main causes, one extremely simple and one complicated.  Ninety-nine times out of a hundred it’ll be the simple one.  People seem to have a strange ego over technical problems: they want to believe it’s a resource conflict that’ll take three reinstalls and a sledgehammer to solve rather than believe they forgot to plug something in.

The simple: it’s just feedback.  Especially if you’re using a mic with speakers (very liberating, but not very controlled) your words are cycling through the system more than once.  Use headphones, or alter your volume and sensitivity settings until your mic isn’t picking up the speakers anymore.

The complicated: there are known issues with certain soundcards, and these are of the super-cyber-sounding movie type.  In one case (the Turtle Beach Santa Cruz card) the physical layout of the circuitry causes signal to leak across the card, in another (some Creative Labs models) incorrect driver operation causes the card to mix a few too many channels together at once, confusing the input and output.  Worse, these problems can be triggered by someone else’s computer doing the mixing - so if you’re sure your headset is A-OK and you only get yourself in stereo when certain people are online, refer them to the Ventrilo FAQ for peace of mind (and gaming).
