Mass Effect Legendary Edition How to Fix Surround Sound in ME1

1. Download openal soft from https://openal-soft.org
2. Put file from Win32/soft_oal.dll as OpenAL32.dll to Windows/SysWOW64 and file from Win64/soft_oal.dll as OpenAL32.dll to Windows/system32, override if necessary
3. Delete OpenAL32.dll from binaries in game directory
4. Put this:

[ISACTAudio.ISACTAudioDevice]

MaxChannels=128

UseEffectsProcessing=True

TimeBetweenHWUpdates=15

MinOggVorbisDurationGame=20

MinOggVorbisDurationEditor=4

DeviceName=

ReserveChannels=2

TotalAvailableChannels=128

UseEffectsProcessing=True

To BIOEngine.ini in config directory in path like Mass Effect Legendary Edition\Game\ME1\BioGame\Config, make it read-only so game doesn’t override it. There should be already section like ISACTAudio.ISACTAudioDevice so put it there

5. Run alsoft-config.exe from openal-soft-{version}-bin\alsoft-config and set your desired channels – in my case it’s 7.1 and click apply, you can try other options, whatever seem to be better for you
6. (Optionally) go to %appdata%, there should be file alsoft.ini and you can try adding two options there:

volume-adjust = 6

front-stablizer=true

volume-adjust increases overall sound volume -24 to 24
front-stablizer – mixes sound from left and right channel to center
7. Just run a game, you should have surround sound working fine now
8. If it doesn’t work try restarting your PC
9. Also it might work if you replace dll only in a binaries folder – but i didn’t try it
