Loudspeaker volume too low during calls

[fds83]

Hello, I use a brand new Xperia 10 and it's not useable for phone calls, the sound is too low when I use the loundspeaker. I've read that this problem is caused by Android 9 Pie.

Anyone have this issue ?

I have the same issue.

Sent myself an audiofile with Telegram, it sounds okay, but when i use this file as a ringtone - the sound is awfull. Also tried multiple bitrates.

What can i do to solve this?
