Setting issues with Z270a or HDMI audio display fluctuations.
Setting issues with Z270a or HDMI audio display fluctuations.
Windows 10 ASUS 1302 BIOS for Z270a connected through HDMI to a TV (without channels acting as the monitor). Audio drivers are just installed, display drivers are nearly ready, but audio stopped working for Train Sim World 6 and Train Sim Classic. When switching audio outputs mid-game, the session loses sound completely until you restart, even after changing back to the original setting. The flickering in the bottom-right corner shows output changes at the moment the game launches and switches to the loading screen. Adjusting Mixer settings via a right-click in the taskbar often hides the HDMI option, revealing only Realtek Mixer, which doesn’t update unless you select it again. My Realtek never plays audio when selected before, and it hasn’t caused problems until I installed new drivers recently (see my latest post for details). Wireless headphones connected through a USB3 port work fine with all XBOX App activities. The HDMI output is set to Default, and Default Communication isn’t used. The Realtek Driver’s access rights were removed recently. I’ve swapped HDMI cables, removed the splitter, and even performed a hard reset by unplugging from TV, PC, and then the PC from the wall. Still, only one successful run was found before failures returned each time. The most puzzling part is that HDMI works with both YouTube and ETS2.
I only began experiencing problems recently. ETS2 was released long before TSW6, yet I believe SCS does a solid job. TSW6 is set for 2025, but much of its content comes from earlier versions, around 2018. It’s hard to find a clear reason why the HDMI (connected straight into the drive) would suddenly behave oddly. Up to my last check, I had it as default, the XBOX app configured for HDMI output, and the game didn’t have its own output settings—it just communicates with the XBOX app. I might try disabling Realtek Output, but that doesn’t resolve the issue even when selected. For help, I tried using Chrome to watch the Mixer settings. I noticed that when the HDMI had a brief glitch during a video, the Realtek Output still interacted with Chrome, but only through the HDMI output setting. When it didn’t respond at all, the game wouldn’t show any volume bars on any of the three screens. Additional note: The Realtek appears to work normally at launch, didn’t flicker, and after a flicker it still shows as dead in the HDMI output, with no green volume indicators. The driver seems to be trying to use the optical jack instead of the HDMI, and there’s no option in the settings to switch that. The HDMI will also report removal if it flickers while the settings tab is open—like for enhancements or other features.
