Description Alexander Minkin 2024-11-25 20:26:13 UTC

SUMMARY
When I first connected to Yandex Station Lite (Яндекс Станция Лайт) speaker via Bluetooth, Pipewire chose an HSP/HFP AG profile (Адаптер аудиогарнитуры (приёмник A2DP и HSP/HFP AG)) by default — it is not supported by this speaker, but still suggested by Pipewire (I think that should be a separate bug, however I do not know where to report it). As a result of this, the speaker didn't show up in audio settings despite being connected via Bluetooth, resulting in inability to change speaker profile with default tools. In the end, I managed to change profile with pavucontrol.

STEPS TO REPRODUCE
1. Connect to a Bluetooth speaker that supports only SBC.
2. Choose HSP/HFP AG profile

OBSERVED RESULT
The speaker is gone from audio settings, it isn't even shown as an inactive device.

EXPECTED RESULT
The speaker should remain in audio settings with ability to switch profiles.

kcm: make inactive detection more robust

a device that has neither sources nor sinks ought to be considered
