Speaker stops working

[Aligosla]

Please tell us some basic information before asking for help:
Model Name: Zenfone 9
Firmware Version: WW-32.2050.2050.34
Rooted or not: No
Frequency of Occurrence: Occasionally
APP Name & APP Version (If your issue relates to the app): Anyone using the speaker
In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.
========================================
The lower speaker stops working, only the upper earpiece plays.

I really don't know why this happens, it is necessary to reboot the device for it to be fixed and it works again
This problem has me rotten! 2 versions ago it happens and they still do not correct it.

Is that happening right after the phone call? If that's the case then it's the same issue as rog 6

It just happened to me without making any calls, I answered a call from my Galaxy Watch. I don't know if it has to do with this

You can see that the audio alternates in the bottom speaker, sometimes it sounds and sometimes it doesn't.
after restarting the device it is fixed

Just happened to me again today after finishing a phone call

How is it possible that no moderator sees this post yet?
