What's this?You probably haven't set it up in
/boot/device.hints
Sorry, I mean when I use the 3.5 hole and an external microphone, it can record voice. But I can't use the internal microphonemicrophone doesnt playback sound, are you checking if it is recording your sound?
you can look at dmesg to determine if your mic is picking up on your device. Another step is to run cat /dev/sndstat to confirm what audio devices you have avialable.Sorry, I mean when I use the 3.5 hole and an external microphone, it can record voice. But I can't use the internal microphone
This is on a thinkpad w520 though.I have a similar issue, I discovered that when I run audacity I can select different input options and that selection seems to get the internal mike selected/working for zoom as well. Very kludgey, but it works. I tried to figure out how to solve it using device.hints but failed.
