No Microphone output in Zoom (Mint 20.1)

[nickmax1]

I recently upgraded from 20 to 20.1 when Zoom was working just fine on my Asus laptop.

Now whatever i try i cant get the microphone to pick up any sound (no one can hear me)

In the sound settings I can clearly see the microphone working as the volume bar moves up and down as I speak in to the speaker, but zoom wont have any of it.

I am not on mute by the way....

Hi nickmax1, and welcome to the forum.

Let's make sure the proper input device is set as the default with this command:

Okay, the unknown at the end of this is probably the source of the trouble:

Code: Select all

	ports:
		analog-input-internal-mic: Internal Microphone (priority 8900, latency offset 0 usec, available: unknown)

Does the mic work in anything other than Zoom?

Some things you could try:

• Delete the files in /home/YourUserName/.config/pulse then run pulseaudio -k in the terminal. Start Zoom and test

• Install pavucontrol and on the Input Devices tab lower the right channel'ss volume slider to zero and test. If you only see one slider, click the lock icon to expose the left and right channels

• If the issue is only in Zoom, don't let it control the microphone settings somewhere in it's settings

[nickmax1]

Thanks that didn't do anything, but I installed the zoom cloud app (zoom meetings? Is that the same thing?) instead of the Google extension and that recognises the microphone fine

[MrEen]

Ahh, apparently another issue with Zoom itself. I don't use it myself, so can't offer pretty much anything about it. It seems like almost every Zoom issue is different than the last one. And what works for one person often doesn't work for the next.

[nickmax1]

Thanks. I do get loads of Initramfs unpacking failed errors on boot with 20.1, not sure if they are related to issues I have.
They aren't on the screen long enough for me to capture them though

Wish Linux had an android style factory reset button so I could just start again

If you made a Timeshift snapshot before upgrading, you can always revert to that.

[nickmax1]

Nope. Silly me.

Night have to just start all over with a USB.

Bit archaic if you ask me

[MrEen]

Sorry. But you will try Timeshift the next time you upgrade, won't you?
