Hello. I just realized that many onboard Realtek ALC codecs supports EAX 1 and 2. Through some DSOAL and OpenAL software some games could use that audio extensions. I didnt try it in d2r, but in original d2 my audigy 2 zs (actually it supports EAX 4.0 but utilize only 2.0 version in Diablo 2) turned sound into awesome level. Much better than any 7.1 surround even with headphones. I will try it with d2r, but not now because i’m leaving my town for a while and will not have access to games. Btw you could try it and make a good game even better (and more close to original Diablo 2 in terms of sound effects)
Try it only if experienced user (I didnt try it for now):
1. Download and install OpenAL (https://openal.org/downloads/) 2. Download Unlocker (https://unlocker-official.ru/) and DSOAL (https://community.pcgamingwiki.com/files/file/1363-dsoal/) 3. Use Unlocker to rename original dsound.dll at C:\Windows\SysWOW64 4. Drag files dsoal-aldrv.dll and dsound.dll into C:\Windows\SysWOW64 with replace or in game folder
