Bluetooth sluchatka se neumí znovu připojit
« kdy: 21. 03. 2021, 00:29:45 »
Mám problém s jedněmi bluetooth sluchátky. Druhá sluchátka, co mám se chovají baz problémů.

Linux Mint 20.1 mate
Sluchátka hid-generic 0005:05D6:000A.0002: input,hidraw0: BLUETOOTH HID v2.40 Device [SBKP 4 A1] on 28:b2:bd:8a:41:2e
Verze bluez je Version: 5.53-0ubuntu3

Pokud sluchátka nově spáruju s počítačem, tak fungují v pořádku
Když je následně vypnu a za chvíli zapnu, tak dole ikona píše connected to SBKP 4 A1, ale audio do sluchátek nejde. V pavucontrol bluetooth nevidím. Mačkání tlačítka play/pause na sluchátkách nepomůže.
Po asi minutě se sluchátka samy odpojí.
Když v buetooth kliknu na zařízení + na connection, tak se opět připojí a většinou to už jde. Stejně tak, když v době, kdy jsou ještě připojená kliknu na connection (odpojím) a opět connection (připojím), tak zvuk jde.

Jak udělám, aby se po zapnutí sluchátek samy připojily (stejně jako se mi tak chovají druhá sluchátka)? Kde najdu bluetooth log, abych viděl, co se tam děje?

Díky za nasměrování

Zapnu pocitac

pustim dmesg, abych videl, co je posledni zapis

Zapnu bluetooth sluchatka. Ikonka vpravo dole pise Bluetooth:Connected to SBKP 4 A1
V dmesg neni zadny novy zaznam

Kliknu na bluetooth a vidim, ze jsou sluchatka connected. Kliknu na odpojit.
V dmesg neni zadny novy zaznam

Kliknu znovu v bluetooth na sluchatka a connect.
V dmesg se objevi
[12007.898043] input: SBKP 4 A1 (AVRCP) as /devices/virtual/input/input34
