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?

Does this help:
