Bug ID: 491908
Summary: Volume level reset to 100% after screen is turned off
Classification: Plasma
Product: plasma-pa
Version: 6.1.2
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org

Target Milestone: ---
SUMMARY
I think this is related to the already reported Bug 490017, but I open this one
since there are two different issues so it's easy to track, although I suspect
the underlying bug is causing both. I also found out a way to reliably
reproduce the issue all the times.
The problem is that no matter what the volume is (it can be muted, 10%, etc.),
after the screen is turned off (e.g., by pressing Esc after locking the
screen), the volume after logging back in is always 100%.
This happens whenever my laptop is connected to an external screen or docking
station.
STEPS TO REPRODUCE
1. Connect laptop to an external screen with HDMI/DP or via a docking station
2. Change volume to any desired value (or mute the HDMI/DP device)
3. Lock the screen (Super + L)
4. Press Esc (this turns off the screen)
5. Press Enter to wake up the screen
6. Log in and observe volume of HDMI/DP, which is now 100%
OBSERVED RESULT
Volume level not restored after screen turns off. This does not happen if
session is locked, but screen never turns off (via Esc or after 1 minute by
default). In addition, built-in laptop speakers are not visible (see Bug
490017).
EXPECTED RESULT
Volume level is restored independently if the screen turns off or not. Also,
the built-in speaker should be listed, and the user could choose the audio
output to be the built-in speaker rather than the external device.
