8888/2 worked for me. Big thanks for that!
I will check the speaker assignment on the device. I will report. If need be I will install an amplifier for the loudspeakers.
In any case, thanks so far for the help.
I have one last question. How can I reactivate the weather app?
What I know about that....instruction where to connect to wifi and push the weather symbol on the screen...also that you needed to rename your wifi hotspot, but I managed to activate it without that renaming.
This was the instruction:
After you update everything, we also need to enable the Weather APK, please connect your cell phone wifi hotspot name as FYQP5QRG and YOU connect the player wifi to your cell phone hotspot, and then it will die Weather - Activate APK. If you are using an iPhone, please don't connect your iPhone to our player via Bluetooth before you enable Weather APK. This is very important. After enabling the Weather APK, you can connect your iPhone normally via Bluetooth.
Another thing, on first page on this thread you have a link to the firmware, you find information there....or the newly found webste https://autofather.com/
Here you can also find handfull information.
