Mass Effect Legendary Edition – Surround Sound Fix

Because Bioware again shipped some broken, old OpenAL32.dll where surround is not working properly here are steps to fix it.

Surround Sound Fix: Steps

  • Download Openal Soft from
  • 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.
  • Delete OpenAL32.dll from binaries in game directory.
  • Put this:


To BIOEngine.ini in config directory in path like Mass Effect Legendary EditionGameME1BioGameConfig, make it read-only so game doesn’t override it. There should be already section like ISACTAudio.ISACTAudioDevice so put it there.

  • Run alsoft-config.exe from openal-soft-{version}-binalsoft-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.
  • (Optionally) go to %appdata%, there should be file alsoft.ini and you can try adding two options there.

volume-adjust = 6

Volume-Adjust increases overall sound volume -24 to 24 and Front-Stablizer mixes sound from left and right channel to center.

  • Just run a game, you should have surround sound working fine now.
  • If it doesn’t work try restarting your PC.
  • Also it might work if you replace dll only in a binaries folder – but i didn’t try it.
