Known sound issues in Halo: Combat Evolved (829477)


The information in this article applies to:

  • Microsoft Halo: Combat Evolved

SYMPTOMS

Microsoft Halo: Combat Evolved uses a self-contained set of codices to play back both video and sound. Halo does not install any codices nor does it use any codices from the Microsoft Windows system directories. A codec (compression/decompression) is a tool that allows the correct playback of sound and video. This article only addresses sound codices.

Note The plural of codec is codices.

If you are experiencing an issue that is not listed in this article, you may have to remove and reinstall the game to obtain fresh versions of the Halo codices.

When you play Halo, you may experience one or more of the following symptoms with sounds in the game:
  • Sounds may not be played.
  • Sounds may be played quietly.
  • Sounds may be distorted.

CAUSE

This behavior may occur if one or more of the following conditions are true:
  • The sound driver for your sound card is outdated.
  • Your sound card does not support the required hardware features that you must have to play sounds in the game.
  • The game is not correctly configured to play sounds.

RESOLUTION

To resolve the behaviors that are listed in the "Symptoms" section of this article, use one or more of the following methods in the order that they appear.

Method 1: Check the speaker connections and volume

Make sure that you connect your speakers correctly to your computer and that you turn up the volume on the speakers and in Windows.

Method 2: Configure the sound settings in the game

To configure the sound settings in the game, see the "More information" section of this article. Typically, when you lower a setting or when you turn off a setting, it may increase performance of the game but may reduce the quality of sound.

Method 3: Update the sound driver for your sound card

To update your sound driver, contact the manufacturer of your sound card.

General audio issues

Make sure that your speaker mode is set to match the type of speaker output on your computer. Your speaker mode may not match the type of speaker output on your computer if you switch back and forth between listening to headphones and listening to 4.1/5.1 speakers.

Note Because there are several versions of Microsoft Windows, the following steps may be different on your computer. If they are, see your product documentation to complete these steps.

If your speaker mode is not correct, 3D sounds may be heard incorrectly or not at all. To set your speaker mode, follow these steps:
  1. Click Start, and then click Control Panel.
  2. Click Sounds, Speech and Audio Devices, and then click Sounds and Audio Devices.
  3. In the Speaker Settings pane, click Advanced.
  4. In the Speaker Setup drop-down menu, click the speaker setup that matches your current speaker setup.
  5. Click OK, and then click OK again.

MORE INFORMATION

You can adjust a range of sound options in Halo. The following table describes these features and the potential results of adjusting them.

SoundDescriptionSetting
Master VolumeSets the master volume level.Ranges from 0 to 10, with 0 being mute and 10 being the loudest.
The default is 10.
Effect Volume Sets the volume level of the game sound effects.Ranges from 0 to 10, with 0 being mute and 10 being the loudest.
The default is 10.
Music Volume Sets the music volume.Ranges from 0 to 10, with 0 being mute and 10 being the loudest.
The default is 8.
Hardware AccelerationThe user can adjust the sounds so that they will be processed either by the hardware buffers on the sound card or by the software buffers in DirectX. If hardware buffers are available they may provide better performance and higher sound quality. Yes - use the hardware buffers.
No - do not use the hardware buffers.
The default is determined by the computer's sound hardware.
Sound Quality The user can adjust the type and quality of sound playback.High provides the best quality for a fast CPU. High adds 3D positioning to the sounds so that a sound to the left of your character will primarily come from the left speaker. Normal balances quality and performance and adds Doppler effects. Doppler effects cause sounds to increase in pitch as they come closer, like the whistle on a train. Low provides the best quality for a slower CPU. The default is determined by the computer's sound hardware.
Environmental Sound Enables the effect of having the sounds in the game bounce or echo off of surrounding surfaces. This adds depth to the sounds but can require a great deal of processing power on the soundcard. On - Turns environmental sounds on.
Off - Turns environmental sounds off.
Sound Variety The user can adjust the number of different sounds that will be played during the course of the game.High provides the best quality for a fast CPU. Medium balances quality and performance. Low provides the best quality for a slow computer.
