Arylic S10 randomly changes volume

Arylic S10. Connects to Wi-Fi, can listen to Internet stations, can listen to music from a PC via Foobar2000. The white LED blinks very quickly, then stops, then starts to randomly decrease or increase the volume! And then the S10 just reboots with a complete reset of the settings and you have to reconnect to Wi-Fi. In Bluetooth mode, the volume also randomly decreases or increases. What’s the problem???
