Moving over from random computery things thread.
This would be a rant if ICBA, but I can't.
After much swearing my small HP box is now happily(?) running Manjaro (Linux). Everything apart from one thing seems to be fine. The one thing involves video calls either via Zoom or Messenger.
I can hear them but they can't hear me.
There's nothing wrong with the mic on the webcam (it's just cheap and crappy but I can record with it no problem). If I check it with the setup page on Zoom then it says it's working fine. But not when I try to speak to someone. The signal's there but it ain't going anywhere. Obviously it's not muted and volume's way up. Up to a couple of weeks ago it all worked fine but then Ubuntu decided it didn't want to play anymore so I went non-debian.
I've run out of things to try. Anyone got any ideas? Please.
Do you know if manjaro using pulse audio?
Yes, it is.
Might I suggest you explain the issue in a seperate thread and include with the first post the output of running pacmd list-sources in the terminal?
BTW I've not had a problem like this before, so I've no idea what the solution is going to be! Could you also say whether you are using Zoom in the browser or the Zoom application.
Will do. Thanks.
I've tried both methods of using Zoom and also Facebook Messenger video. All have the same issue.

If Zoom's getting the audio in test mode, it doesn't sound like a microphone problem. ???

Well yes. I can speak into the mic and record it but it doesn't want to send it over the interwebs.

That's got to be Zoom's fault, shirley? Rather than Pulseaudio or whatever's breaking sound on Linux this month. *boggle*

Just in case anyone was wondering, it's not peculiar to the Isle of Sheppey. My phone works fine with all of it going through the same internet connection. It's just this stupid HP computer - although I fail to see how it could be a hardware problem. I'd hazard a guess that it's some little change that I need to make somewhere but I'm not seeing it.

That's where it stops making sense...

We have a friend who suffers endless problems with Zoom and transmitting her voice. Sometimes it works, sometimes it just doesn't. I will check with her what make her laptop is. She spends inordinate amounts of time fiddling with the settings in both Windows itself and in Zoom.
Her partner's laptop which is also a Windows 10 machine just works.

Are you sure its using the right mic ?
I just tried Zoom on Ubuntu 20.04 and it picked the laptops inbuilt mic and not the headset one. Had to go into the Zoom audio settings and pick the headset mic from the pull down menu.
-
I've only got one mic. When I test it in Zoom it shows up and works fine.
-

Not suggesting it is, I just wanted to see the devices PulseAudio recognised and which is the current.
I've had a great deal of fun with this lately, with output (sinks) rather than inputs (sources).

Sorry if I'm being terribly stupid here, but I think this might be the combination of the selected source device being "alsa_output.pci-0000_00_1f.3.analog-stereo.monitor" (index: 0, denoted with an asterisk) and the way Zoom plays with microphones.
On a recently rebuilt Debian 10 laptop, I have source index 1 alsa_input.pci-0000_00_1b.0.analog-stereo as the default source and source index 0 alsa_output.pci-0000_00_1b.0.analog-stereo.monitor as a monitor/virtual device. I've changed the monitor/virtual device to be the default sink as per nicknack's setup with pacmd set-default-source 0 and I can reproduce the issue. If I revert back, it is fine again: pacmd set-default-source 1
I'm an absolutely novice when it comes to doing anything with PulseAudio, but it seems odd to me that the virtual/monitor device is the default source (input)? I could 100% missing the point.

I'll give it a go tomorrow. Ta.

Someone in my hiking club (FOTP) has microphone problems on Zoom in Linux.
Starts as an inaudible tinny version of his voice before it becomes normal after a few seconds

It works!
Thanks very much for that.
Linux being stupid about how it handles audio again I suppose.
In the Pulseaudio GUI before, it looked like it was giving me an option to switch between the two but it was stuck on one and wouldn't change. I assumed that was correct for what it was trying to do. I might have known the terminal would be involved. Having effected the change the option is no longer there in the GUI.

The next step will be add the following line to the end of /etc/pulse/default.pa to make it persist a reboot. I think the following should do it (on account I'm not sure it needs the angled brackets or not):
set-default-source alsa_input.pci-0000_00_1f.3.analog-stereo
You will need to do something like:
sudo nano /etc/pulse/default.pa
or:
sudo vi /etc/pulse/default.pa
to open the file for editing, substituting nano/vi for your favourite text editor. If you don't have one, I think nano should do.

Also noticed I didn't see the webcam microphone in the list of inputs (sinks). The microphone you are using looks like it is build into the laptop or plugged into a jack on the laptop?

If you want to leave the system files unchanged, you can create .config/pulse/default.pa in your home directory. It needs to start with the line:
.include /etc/pulse/default.pa
followed by the set-default-source line.

It's not a laptop it's a small form factor PC (HP) and, yes, it's a separate webcam and mic.
Thanks for the suggestions all. I'll have a fiddle with the defaults.
