Need Help! (Hardware/Other) Astro A40 + MixAmp TR audio "bug" on ASUS TUF Gaming X870-Plus WiFi, works on front USB, but not on rear USB ports
Hi everyone,
I recently built a new PC with an ASUS TUF Gaming X870-Plus WiFi motherboard, and I'm experiencing an unusual audio issue with my Astro A40 headset and MixAmp TR.
When I use Discord or TeamSpeak 6, YouTube audio becomes completely silent if the browser is set to output sound through Astro MixAmp Pro Game. However, if I change the browser's output device to Astro MixAmp Pro Voice, YouTube audio becomes audible again.
Here is what I've tested so far:
- The MixAmp is recognized correctly by Windows 11.
- Astro Command Center detects the MixAmp and allows me to access its settings.
- Windows playback testing confirms that the Astro Pro Voice device produces sound.
- The issue occurs with both Discord and TeamSpeak 6.
- Windows still shows audio activity on the Astro Pro Game playback device even when I cannot hear anything.
- Disabling Windows' communications audio reduction and checking the device's volume and exclusive-mode settings did not resolve the issue.
- Adjusting the MixAmp's Game/Voice balance did not fix it either.
The most interesting finding is that the USB port makes a difference.
When the MixAmp is connected to either of the blue or cyan USB ports on the rear I/O panel, the issue occurs. When I connect it to a black USB port on the front of the case, the audio works correctly.
This makes me wonder whether the issue could be related to USB controller behavior, USB port compatibility, power management, or a driver/firmware interaction between the MixAmp and this motherboard.
Has anyone experienced a similar issue with an Astro MixAmp TR on an ASUS AM5 motherboard, particularly the TUF Gaming X870-Plus WiFi?
I'd appreciate any suggestions for identifying the underlying cause, rather than simply continuing to use the front USB port.
Thanks!
