8.1 Update screwing up the loudspeaker!

[anon(8150199)]

My Lumia 920 (on Lumia Black) got the update on Monday. When I put it on the charging plate on that day I didn't notice any sound, but thought it was due to some changes in the settings. But later into the week I started noticing that there's no ringing at all, and realized the whole loudspeaker is dud due to the update! I haven't got Cyan yet, so should I just flash the firmware?

I haven't had this problem on my ATT 920 on Black. Is it possible you are in "quiet hours"?

Nope. The whole loudspeaker is dud, not just ringing.
