Webcam works but microphone not picking up sound

I'm using a Dell Inspiron 15 5510 laptop and never used a webcam before so I'm a bit in the dark here. I've been using Zoom to do some education stuff but I found out very quickly that my microphone doesn't work properly when I'm on Zoom. I can use my earbuds/mic instead by plugging them in and then my audience can hear me.

It's not so bad really but there have been times I'd prefer not to use earbuds and my little built-in microphone on them but rather use the mic on the laptop's camera instead. I've got pipewire and alsa installed as well as some sort of pulse audio module I believe.

Here's the hardware I'm working with:

↪ lsusb
Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 003 Device 003: ID 0c45:6a10 Microdia Integrated_Webcam_HD
Bus 003 Device 002: ID 27c6:639c Shenzhen Goodix Technology Co.,Ltd. Goodix USB2.0 MISC
Bus 003 Device 004: ID 8087:0026 Intel Corp. AX201 Bluetooth
Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

lsmod |grep -i uv
uvcvideo              143360  0
videobuf2_vmalloc      20480  1 uvcvideo
videobuf2_v4l2         40960  1 uvcvideo
videobuf2_common       81920  4 videobuf2_vmalloc,videobuf2_v4l2,uvcvideo,videobuf2_memops
videodev              299008  3 videobuf2_v4l2,uvcvideo,videobuf2_common
mc                     69632  4 videodev,videobuf2_v4l2,uvcvideo,videobuf2_common

Not sure what else to provide that would help.

Re: Webcam works but microphone not picking up sound

Stuff of audio level relevance would help, uvc is just for the video. Audio is handled via the standard snd_usb_audio module.

arecord -l
sudo dmesg | grep -iE 'usb'
#During a "broken" zoom test call
sudo fuser -v /dev/snd/*
pactl list cards
pactl list sources
pactl list source-outputs

Generally zoom relatively aggressively tries to stick to the device it's configured to stick to, so check it's settings and make sure the USB/webcam recording device is selected as the input device.

Re: Webcam works but microphone not picking up sound

Ah hi again V1del, and thank you again. I'll do my best to set up a test Zoom call and get some information. I am, unfortunately, not well-versed in audio/webcam things.
