I found the driver in the forum and solved the problem
but spent a lot of time
why your company doesn’t say anything about it when downloading the upgrade it’s a headache for the owners of amplifiers and you also need to indicate that all kinds of problems often occur and you can find the answers here and there
Another question is why it is so difficult to connect via bluetooth to a phone or tablet and all the time reconnect and reconnect???
Is this what is done in China? or so stupid engineers who can’t fix these problems and produce defective products? shame on the company new technology and software poor
Today, any bluetooth headphones work much better than the bluetooth in your amplifier
