Hello! I bought my Redmi Note 8T about a year ago, and like 2 or 3 months ago it started having a weird problem, when I would enable my loudspeaker when on a mobile call, my microphone would go silent. Happened only when I enabled my loudspeaker. I thought nothing of it, since I rarely use loudspeaker anyway, so I just let it slide, WhatsApp video calls (where loudspeaker is in use) were always normal, but as of today, my microphone isn't working on WhatsApp video calls either. Normal voice calls, which don't use my loudspeaker, my mic works normally, but if I start a video call, my loudspeaker is in use and my microphone isn't working, only emitting a thudding sound once in a while. Anyone had this problem before?
