As stated in the subject, it's a random seldom behavior. Sometimes after a key press which should have a voice prompt feedback, nothing is played, but the speaker emits a silent noice as it does when any audio is played, and it doesn't stop until next audio request overrides that state.
Observed on GD77 with R2020.09.12 and R2020.10.01, I didn't try previous releases.
Steps to reproduce.
- prompts set to level 3 (didn't test on level 1)
- press "green" to get to menu
- arrow down until you encounter the bug, probably not more than ten rounds; you don't have to wait until the announcement finishes
It doesn't happen just in the menu, but it is the easiest way how to reproduce it.
