PC Gaming Surround Sound Round-up
Below is a list containing PC games, the programming API used for their audio processing, the final result of the audio output, and some [possibly opinionated] comments. You may notice that an API doesn't necessarily create a limitation but the exception to this is OpenAL, which completely lacks the ability to provide any type of discrete LFE output in games; all other APIs are fully capable of this but some developers fail to implement that functionality and also fail to implement support for anything over 5-channel output.
- LFE (low-frequency effect) - The LFE channel is designated as a channel that carries lower-frequency audio. While, according to Dolby, this channel isn't strictly for subwoofers, the LFE channel in a PC audio context is typically directed to the subwoofer. This is sometimes overlooked in development which results in games not delivering bass to the subwoofer. The LFE channel is represented by the ".1" when discussing "5.1" or "7.1". If I've listed a game as "5.0" that means that no LFE channel is present.
- ALchemy - ALchemy is an application that works with Creative sound cards to restore DirectSound functionality in games designed to work with Windows XP's audio functionality but that no longer properly function in Windows Vista and Windows 7 as a result of changes made to the Windows operating system after Windows Vista. Most modern games don't require ALchemy while Valve's Source-based games still require ALchemy for their games to properly support 7-channel audio.
I'm using a Creative Labs X-Fi Titanium Fatal1ty PCI-E card connected to an Onkyo TX-SR605 receiver via analog connection; 8-channel direct input into the receiver. Windows 8 64bit is the operating system.
To ensure no interference with the results, these steps were taken:
- The audio receiver is using no surround matrixing. This feature is actually not available on the TX-SR605 7.1 while taking input from the analog inputs and no bass redirection occurs via the receiver. Audio is output exactly as it is received from the sound card.
- Sound card enhancements are disabled: CMSS-3D; Crystalizer; anything that changes the audio outside of the game's control.
- Bass redirection is disabled via the Creative Console Launcher.
- Speakers are set to 7.1 via the Creative Console Launcher.
- Creative Console Launcher is set to Game Mode.
- Speakers are set to 7.1 via Windows Sound setting (Control Panel).
- Front and surround speakers are set to full-range via Windows Sound setting.
The Games Tested
The games I've tested are simply the games I've had access to. Much older games may be omitted since multi-channel audio wasn't common before 2000 and testing is typically limited to action games that I believe should support surround sound. If I come across a game that suprisingly supports mult-channel sound then I'll add it to the list; Toki Tori is an example of this. Toki Tori is a 2D puzzle game but has quite good audio effects and even supports 7-channel audio while bigger-name titles barely even support 6-channel audio. See the list!

- OpenAL doesn't appear to support in-game LFE mixing. OpenAL can send audio to the LFE if the audio file (WAV, OGG) specifies the channel but I've never played an OpenAL game that output audio to the LFE.
- Miles Sound System is used by Source (Valve) games and basically routes itself through other APIs. In Windows, or at least for Source games, it's routing through DirectSound so adding Source games to ALchemy gets your 7.0 functionality in Vista/7 where as you would only get 5.0 sound without ALchemy. In Linux, Miles routes through OpenAL.
- Implementation of the LFE channel seems to be often overlooked which could be a result of how their test equipment is setup. While direct analog connections don't redirect bass unless the source says to do so (actually varies by receiver), HDMI connections may redirect the bass at the destination/receiver.
- After discussing the issue with different people, I've found that lack of support for certain speaker configurations may be a result of programmers not thoroughly implementing the features and development studios only having 5.1 setups to test on.
- Wwise initially only supported up to a 5.1 speaker configuration. As of 7 October 2013, Wwise supports 7.1 audio. Any game developed with Wwise version 2013.2 that does not support 7.1 audio will be assumed to have been developed by INCOMPETENT SLACKERS.
- "LFE mixing is done very well" If I made a positive comment about the LFE, it means I thought that it was well-balanced and used appropriately. I understand that volume adjustments on my end can make this judgement unreliable but I feel confident that my subwoofer volume is reasonably set.
- Dead Island likes to throw a fit when I have 7.1 enabled in Windows. It mostly has buggy sound but it occasionally works; I used to just close and restart the game until it worked but that rarely works. If I set Windows to 5.1 sound then I get no trouble from Dead Island.
- Dead Rising 2 games have a bug that prevent them from starting if your audio device is set to operate at greater than 48kHz. Set your playback device to 48kHz or lower to get the game to run.
- Dead Space games appear to use a proprietary audio engine developed by EA (or Phenomic?), RwAudioCore. This particular audio engine appears to have various features such as 7.1 (and LFE) but they weren't used. I'd say it's worth it to use bass re-direction for DS 1 and 2 because there are many sound effects that mix in good to the sub and add to the intensity of the audio. Looks like as of Battlefield 4 they're calling it "EAAudioCore".
- Dishonored is technically 5.1, it outputs audio to all speakers in a 5.1 configuration, but it only outputs some low volume effects to the center channel. Character voices, gunfire, and footsteps that would be played in the center channel are played in the two front speakers, it's essentially a 4.1 game that plays auxiliary effects in the center speaker. This issue also appears present in the Xbox 360 version.
- DOOM 3 was originally a DirectSound game but a later patch added OpenAL support. DOOM 3 defaults to OpenAL unless you don't have OpenAL installed on your system, then it falls back to using DirectSound.
- Gears of War might be the only OpenAL game I've seen that initialized to 5 instead of 7 channel surround. Afterthought: This game may be using its own OpenAL DLL located in the game directory. Removing it and forcing the game to use my system's OpenAL DLL may have allowed it to use 7 channels. I don't care to reinstall the game to test this.
- Hotline Miami was originally a DirectSound game with 2.0 output but was later migrated to OpenAL. The move to OpenAL was probably because they ported the game to other platforms (OSX, Linux, PS3, Vita) and OpenAL was the better choice for portability. While it does playback audio in 7-channel surround, there doesn't seem to be any particular method for sound placement. The music is in the front two speakers, certain sound effects play strictly in the side speakers and others play strictly in the rear speakers.
- Mirror's Edge seems to be slightly buggy as far as hardware detection goes. In the game's audio options, select Hardware for the audio device. Exit the game and then navigate to the TdEngine.ini file located in Documents\EA Games\Mirror's Edge\TdGame\Config. You'll find "DeviceName=" under the ALAudio.ALAudioDevice section. Delete any text after "DeviceName=" and it should then properly output in 7-channel surround. This actually seems to be common with some Unreal Engine games that use OpenAL.
- Resident Evil 4, the 2014 PC re-release, outputs to 7.1 speakers in some cases but the sound effects are all mono and do not move based on the player's position. Music, and anything else that was recorded in stereo, plays back in stereo. Hopefully we'll see this fixed.
- Serious Sam 3 can be configured to use several different audio APIs in its configuration file; I'd recommend sticking with XAudio2. Also, the LFE volume in this game is disgustingly loud compared to anything else I've played.
Using Bass Re-direction
If you really want the added effect of a subwoofer in games that don't automatically mix to the subwoofer, you're going to need to use bass re-direction. When enabling bass re-direction you're also likely going to need to adjust your subwoofer volume level so take into consideration that toggling bass re-direction may affect your subwoofer's output and you may need to adjust the subwoofer's volume level to balance its volume with the speakers. Games will vary when re-directing bass; some will sound fine with the sub at higher volumes and others will sound messy. For me, Dead Space 1 and 2 and Amnesia sounded fine with my initial setting but Borderlands 2 sounded messy until I lowered the volume more. While I would prefer to not have to use bass re-direction, I'd hate to miss out on the lower frequencies so I would recommend using bass re-direction for games that leave out the LFE channel.
