Bluetooth speakers don't auto reconnect after return from sleep mode

Support Sound

When Manjaro wakes from the sleep mode or bluetooth just turned off an on, every BT device which was connected before reconnects automatically. Except BT speakers (paired and trusted), which require manual connection each time.

What may be the reason and how to repair?

Bluetooth:
Device-1: Realtek Bluetooth 4.2 Adapter driver: btusb type: USB
Report: btmgmt ID: hci0 state: up bt-v: 4.2

did not find something suspicious in system log.

Bluetooth - Adapter disappears after suspend/resume - ArchWiki

Find vendor [1] and product [2] ID of the adapter

lsusb -tv

Then, use usb_modeswitch to reset the adapter:

sudo usb_modeswitch -R -v [Vendor ID] -p [Product ID]

[1] Vendor ID for Realtek Semiconductor - 0bda

[2] Product ID might be either b009 or b00a or b00b
  Linux Hardware - Realtek Bluetooth 4.2

After latest update I have the same problem with mouse. After sleep or reboot, need to manually forgot old connection and create new with device. Tried to add device as trusted with bluetoothctl. Doesn’t work
