Microphone not functioning since android pie update

[Android Central Question]

I updated my S9 to android pie yesterday and since then, the microphone not working. I can also make or receive calls using an earpiece or switching to speaker option.

Voice operations such as Bixby OK Google also not working unless with the microphone on my earpiece. Any advice please?

try restarting the phone , see if it was a glitch.

I had a similar issue with the earphone (the speaker that you use when answering a call). So if restart doesn't work try to boot into safe mode, check if it works then and then restart - that did the trick for me.
