Problems with Bluetooth & Wireless, if you are using both of them

[Monsteroid]

I am using a Rock 5T 12GB board and have tested multiple Armbian images (24.04, 26.04, and others). Here is my experience so far:

• Armbian current images
  • Audio does not work at all.
  • When I plug in a 3.5 mm headset, nothing happens — no detection, no sound.
  • Bluetooth works, Wi‑Fi does not.
  • I have to manually compile the Realtek rtw89 wireless driver. After compiling, both Wi‑Fi and Bluetooth work, but still no audio output.
• Vendor (Radxa) images
  • Audio works perfectly.
  • When I plug in a headset, the system immediately detects it and asks whether it has a microphone.
  • Sound output through the headset works as expected.
  • However, with the vendor image I cannot use Bluetooth and Wi‑Fi at the same time. According to what I found online, the RTL8852BU chip shares internal resources. I must disable Wi‑Fi to use a Bluetooth mouse and keyboard reliably.
  • Connecting a Bluetooth headset causes an immediate disconnect.
• Feedback from Radxa
  • Radxa confirmed that the Bluetooth/Wi‑Fi coexistence issue is caused by the driver.

Summary

At the moment, I cannot use either the current Armbian images or the vendor images without running into major problems:

Armbian: Wi‑Fi/Bluetooth OK (after manual driver build), but no audio.

Vendor image: Audio OK, but Bluetooth and Wi‑Fi cannot work simultaneously.

Is this a known issue, and am I the only one experiencing these problems?

 

Thanks a lot for your support and help.
