Problem after Android 11 update on Zenfone 6

1- When using apps like: WhatsApp and Google Duo,, in a video or phone call, I can't use the speakerphone. The other person talks and I listen very low. The installation of Android 11 is clean because I did reset on the device. What can I do to fix this error? Is it from the rom or is it from the applications?
