Use Hardware Audio Option Resets itself

[kirakatve]

Hello!

The issue could be that your computer fails to save the config file because the game doesn't have the right permissions. Could you try running it as an administrator?

Otherwise you can go to the following path (or whatever you have set for Steam/GOG/HB):
C:\Program Files (x86)\Steam\steamapps\common\Penumbra Overture\redist\config
-> default_settings.cfg

You can probably adjust the following setting:
<Sound Volume="1.000000" UseSoundHardware="false" MaxSoundChannels="32" StreamUpdateFreq="10" UseThreading="true" MaxMonoChannelsHint="0" MaxStereoChannelsHint="0" />

Hope this helps!
