No microphone input

Hi everybody, I have this Lenovo Yoga 920 laptop running for one or two years now. It is a nice machine, but now when corona grounded I wanted to socialise a little with my daughters by eating together on distance. But I discovered that there was no microphone input to the video conference. I have this morning tried to install different software in order to overcome this problem, but with no luck. If I put in a headphone there is microphone input from the headset. I can't find any settings in the BIOS to enable or disable microphone. How do I find out if the microphone is working at all on this laptop? |< -- Med venlig hilsen Klaus Kolle Teknikumingeniør, B.Sc.EE., e-mail : klaus(a)kolle.dk Master of IT www : www.kolle.dk Asger Jorns Vej 17 Telephone : +4522216044 DK-8600 Silkeborg, Denmark "Man skal ikke tilskrive til sammensværgelser hvad der tilstrækkeligt kan forklares af inkompetence" Poul Henning Kamp Planlægning er tanker om noget man agter at gøre en gang i fremtiden, hvis omstændighederne tillader det.
