SUMMARY

I'm using Oxygen sounds, the best and the only usable sound theme. I set Oxygen-Sys-Log-In-Short.ogg to play when session starts. After update from 5.18 to 5.19.1 I hear only first 1-2 seconds of this sound and then it abruptly ends, as if someone violently plugged the cable of the speakers out.


STEPS TO REPRODUCE
1. Update system from 5.18 to 5.19.1
2. Reboot system and boot into session with Oxygen-Sys-Log-In-Short.ogg as new session sound.

OBSERVED RESULT

I hear only first 1-2 seconds of this sound and then it abruptly ends.

EXPECTED RESULT

The full length of the Oxygen-Sys-Log-In-Short.ogg should be played.

ADDITIONAL INFORMATION

Since oxygen sounds are no longer part of the system, they didn't update with the system, so I first did system update, noticed the issue, updated the oxygen-sounds to 5.19.0-1. Maybe that is the problem that there is no 5.19.1 package yet? In the backend, the sound plays fully and correctly thou.
Reboot didn't help.
