Description Michal Hlavac 2020-05-19 21:26:42 UTC

SUMMARY

I have bose on ear wireless headphones. When no music plays headphones goes to some sleep mode while still connected. This mode is huge battery saver. But with kmail running there are always ON, which means battery drains 

STEPS TO REPRODUCE
1. Connect bluetooth headphones
2. Start kmail

OBSERVED RESULT
Can hear noise in headphones. It looks like kmail opens some sound stream on start.

EXPECTED RESULT
When start kmail, headphones stays off, because no sound plays.

Could be because of QtWebEngine. Please test if this also happens if you start the Falkon browser.

OK, openSUSE Tumbleweed was upgraded to QT 5.15 and problems are gone. I think we can close this issue. Thanks

The right reason was process named speech-dispatcher-dummy. I couldn't find kmail option to disable tts, but this command resolved all problems:
mkdir -p ~/.config/speech-dispatcher && echo "DisableAutoSpawn" >> ~/.config/speech-dispatcher/speechd.conf
