Do you see any chance to get this to work or can someone else help to find a working solution?
In the leading post of this topic, I also indicated under the description of the device:
5. Amlogic Meson6 (AML8726-MX) SoC on Linux kernel v3.10.108 (LTS):
- WeTek_Play | WeTek Play (a.k.a. WP1) with AML8726-MX SoC (1 GB RAM, 4 GB NAND) and a modular removable tuner:
Working services: Power status LED, CPU temperature sensor, Analog+S/PDIF+HDMI audio output, 10/100 Mbps Ethernet, Wireless (2.4 GHz), Bluetooth, RF+IR combo remote control (HID+amremote), HDMI-CEC*, NAND boot**....
* On some TVs, this can cause instability, but in this case it is worth turning it off:
Settings -> System -> Input -> Peripherals -> CEC Adapter
Unfortunately, many features of the WeTek Play (and Meson6-based boxes in general) are far more unstable/unusable than even an S805/S8X2, even though they are based on the same kernel. These include the CEC service, but has also some audio and network based issues, including Bluetooth-related that are either unstable or can cause the box to freeze for no reason, which can only be helped by unplugging/replugging the power adapter.
Therefore, it can only be recommended for basic tasks. For example, WP1 may still be suitable for a headless tvheadend server.
