Mass Effect™ Legendary Edition – Mass Effect 1 Surround Sound Fix

Steps

1. Download openal soft from https://openal-soft.org
2. Put file from Win32/soft_oal.dll as OpenAL32.dll to Windows/WOW64 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=OpenAL Soft
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 // increases overall sound volume
front-stablizer=true // mixes sound from left and right channel to center

7. Just run a game, you should have surround sound working fine now
