Per my reddit thread, and per an email I have now sent to support: I has a sad!
I am trying to play DOS:EE with a friend, but I have no sound after the Larian Studios splash screen. It has worked fine in the past - over a year ago, though. All other application audio is working normally.
I'm running the latest Realtek drivers that are provided on the Asus motherboard website (z790 Apex, Realtek drivers 6.3.9600.2342). Running Windows 11 23H2 (22631.4602). I've read through the support forum and various posts online, and have not found any solution yet. I've seen people say their problem was fixed - but no consistent reasons as to why or how.
Things I have tried are as follows:
* Adjusting audio settings in game creates no sounds.
* Checked the sound mixer to be sure the game is not muted and is set to 100%.
* Tried searching for the AnalysisTool.exe but the dropbox links in forums are 404
* Checked that the headphones are the default audio playback device.
* Disabled all other audio outputs to be sure.
* Sound configuration (sounds > playback > properties > advanced) and changed default format from 24 bit, 48khz to 16 bit, 44.1khz.
* Checked the configuration of speakers in Windows (stereo), and tests proves they're working, as do all other apps.
* Tried it in Windowed, Fake Fullscreen and Fullscreen mode.
* Checked the integrity of the files via Steam.
* Stopped the vast majority of background services, and turned off real time protection from Windows Defender. I turned off non-essential programs (everything besides Steam and Dropbox).
* Uninstalled the game and reinstalled it via Steam.
* Exited out of Steam completely, and started the game directly from the '..\SteamApps\common\Divinity Original Sin\Shipping\EoCApp.exe' program file, by right clicking and running as administrator.
* Right clicked on EoCApp.exe, selected Properties, switched to the compatibility tab and tried both Win 7 and Win 8 compatibility mode.
* Reinstalled Realtek drivers from Asus website and rebooted.
* Started game, waited for splash screen, alt-tabbed and played video to be sure sound was working normally elsewhere. No change in game.
* Deleted all folders & files to reset config in User\Documents\Larian Studios
* While offline, deleted and uninstalled all audio drivers, rebooted, tested, and then reinstalled, tested again.
* Tested it on bluetooth headphones instead of my wired stereo speakers; no change.
* Investigated event viewer to find no clues.
* Exhaled some pointless grumpy noises.
* Sent a dxdiag and this message to Larian's support email.
I am thoroughly stumped at this point.
Any help would be appreciated. Thank you.
