    X570 C8 Dark Hero Missing A-Volute Sound driver solution

    Hi folks,

    Wanted to report that after installing the Realtek drivers available on the support page for the Dark Hero, I was left with an "unknown device" in Device Manager (would only appear after installing the driver).

    I decided to notify Asus AU support about this issue, and was quickly greeted with generic responses, however after I realised I should look at the hardware ID of the unknown device I found it was an "A-Volute SS3 VAD" driver missing (supposedly this comes with Sonic Studio 3 enabled boards' driver packages). Anywho after notifying support again of the identified issues I'm still greeted with "send board back for warranty and re-install windows" generic "support" lmao.

    Also I believe this missing driver is causing an APPCRASH event with DtsApo4Service.exe in Event Viewer, despite that I hadn't installed DTS software. I haven't seen the event since fixing the missing A-Volute driver, but I'll verify in the coming days.

    Anyway thought I should parrot this on this forum so anybody else might find a solution. You can get the driver from another ROG thread here (many thanks to MoKiChu):

    I did try to install Sonic Studio 3 from the Windows Store, but that did not come with the driver - suppose it needs to come down/be bundled with Realtek driver initially.

    You'll want to download the SS3 package and install the INF file from the folder "SS3>OEM_INF_Media" - you'll then see the new device show up as "Sonic Studio Virtual Mixer" under Sound Devices in Device Manager.

    Hope this helps, and perhaps a team member could pick up on this for a more permanent fix
