goto setting>apps>chrome unistall update then reboot your phone
I've found on our polish Xperia forum similiar problem - someone said that in his case, after receiving a call (and stating that the speaker is on) disabling-enabling the speaker 2-3 times has helped him. Receiving next calls was then OK.
