A bit more extensive comparison to go along with the first one. Three settings were tested now, all on the dedicated Creative X-Fi XtremeGamer card:

0:00 – Host OpenAL (Sens_oal.dll) software EAX emulation on the X-Fi XtremeGamer card. Yes, that's right, you can install HOAL even if you're already running a Creative card, it will work! And it even has a higher priority than the hardware-accelerated implementation (move Sens_oal.dll from system32/syswow64 to get back to the native implementation). Due to being software, the quality should be exactly the same as when it was running on the Realtek card.

9:17 – Creative OpenAL (ct_oal.dll) hardware EAX on the X-Fi XtremeGamer card, like last time, but this time EAX volume has been set to 0 dB, so it does not add any additional volume to EAX effects and makes reverb more subtle. Whether that sounds better is a matter of preference.

18:04 – OpenAL Soft (soft_oal.dll) open-source software implementation on the X-Fi XtremeGamer card. It does not support EAX, therefore there is no reverb, and ambient occlusion is close to nonexistent. It also needed an environment variable to be set to work with Unreal II properly, but the next release should have that issue fixed. In the future it may have EAX support, too.

Next up will be comparisons of some non-EAX OpenAL implementations on the integrated Realtek card as well as DirectSound3D implementations.
