Notifications sound bug ("cutted short, chokes") after Android 11

[jbieldutra]

Model Name: ZS630KL
Firmware Version: 18.0610.2101.132
Rooted or not: Not rooted
Frequency of Occurrence: Very Frequently
============================================
My notifications sound cut short, chokes (skip the initial part of the sound, like it is making a effort to reproduce but cannot, and just the final part plays) after the A11 att, happens A LOT and is really annoying. I already sent it to a Autorized Repair Center and they, aparently, changed the FINGERPRINT READER ? At first I tought that was a joke, and of course dont solve the problem, so I think that this is a firmaware bug and came with the update for A11.

Actually, I found a temporary fix, when I activate the external mode the notification sound stop cutting short, runs entirely, but it seems drains a little more battery than usual.

Please try to check if any third party app is triggering this notifications problem what is behaviour with safe mode? If no any changes to behaviour than surely Repair centre will reflash this software version for you which should most probably fix the issue.
Unfortunatly you have to give a visit to service centre again.
Thanks!

Unfortunately, the only thing you can do is to talk to them and send it in again

Uhm, this was already reported here: https://zentalk.asus.com/en/discussion/44315/notification-sound-clips-and-distorts-after-android-11-...
jbieldutra even posted there but it seems the thread is abandoned?
If this issue is apparent to many users just after updating I don't see how sending to repair will help.
I also have this issue by the way.
Edit: Just confirmed this also happens to ringtones. First ~0.5 second doesn't play. Consequent sounds play fine, you have to wait a feel seconds to reproduce this issue again. This can be tested by using the Sound settings.

...anyways, this also happens with ringtones. You can reproduce this issue through the sound settings.
Safe mode doesn't change this behavior.
Edit: I can confirm that using external mode """fixes""" this issue.
