Microphone disapearing randomly from input devices

English Hardware
1

…since a recent update, i don’t know exactly which update causes this.

when i join a discord call my mic can randomly disapears from the list, meaning that people stop hearing me suddently, i haven’t found any way to reproduce the issue, i don’t know what triggers it.

the mic is working perfectly fine in itself, it’s a USB standard microphone,
the only « fix » is to unplug and re-plug the mic hoping it shows up, because sometimes it doesn’t show up in the list after reconnecting so i have to do it multiple times. OR reboot the PC

is anyone having the same issue ?

No, not aware I have this problem but I am using the microphone only now and then.

For your problem, before starting the call, execute on the console “dmesg --follow”, give some enters to create some blank lines and check what is happening.

Share here everything that is printed out after to empty lines.

It’s difficult to make a conclusive diagnosis with the limited information provided, but it might be due to USB power management settings that can be adjusted via the motherboards UEFI BIOS. I’d start with checking that out first.

FWIW, I’ve seen a coupe of threads where users reported that the ErP (energy related products) setting in the BIOS needed to be turned on. YMMV.

i haven’t changed any setting in my BIOS in months, this issue appeared last week after an update so i doubt that the BIOS settings could be the cause, however i did check the setting and besides ERP being disabled as usual (default setting), there is no power saving setting or anything that could cause the device to turn off for any reason

the issue didn’t appear yesterday, and today as soon as i wanted to use my mic i’ve checked the list, and boom, the mic isn’t there,

however it does appear in lsusb and dmesg

well dmesg doesn’t tell me anything interesting, i’ve disconnected and reconnected the device multiple times in a row

running usbreset temporarily fixed the problem

usbreset no longer fixes the issue… wtf is happening

updated to the latest release, nothing changed

You mentioned that lsusb still shows the device present when inactive and unavailable. Let’s see if it is still present as far as ALSA is concerned. Run amixer, press F6 and choose the appropriate device to view the relevant mic control(s).

Alternatively, view using amixer -cX where X is the card number associated with the USB mic. You can determine that using arecord -l.

Next check if PulseAudio (or its wrapper) reports the device using

pactl list sources

well it looks like the device still shows up before i had to reset the usb device again,

…and what about the pactl command output I requested?

ah yeah sorry i forgot to include it

after starting blender, the same thing happened with my headset, i had to run usbreset again otherwise it wouldn’t show up as well

13

At the time that you ran pactl list sources it was active?

Ports:
                analog-input-mic: Microphone (type: Mic, priority: 8700, availability unknown)
        Active Port: analog-input-mic

If you run pavucontrol are you able to select the appropriate ‘configuration’ profile first, and then select the mic as an input source?

14

At the time that you ran pactl list sources it was active?

no it wasn’t, the issue was present so the device was missing from the input device list in plasma

i’ll see about pavucontrol, i have to wait for the problem to show up every time

when the problems happens, the device won’t show up in pavucontrol either

after running usbreset it shows up immediately here and also in plasma

running blender triggers this issue immediately, discord can also trigger it but it seems more random and takes a longer time

16

It does also not say me much but that is because it show what happens when you disconnected and reconnected the device multiple times in a row which does not capture the problem.

Please leave it running long and capture and or more of the events where the device disappears. Share the log not via a screenshot but just as text, use Ctrl-E /preformatted text to format it.

17

ok i’ll send preformmated text instead of screenshots

tho, every time i reproduce the issue (works every time with blender), literally nothing happens in dmesg, not a single line changes, yet the device disapears from the list as soon as i launch blender.

i’ve made a short clip that shows the problem hopefully more in detail

18

Tanks for the video, agreed that dmesg does not show anything useful but journalctl does.

I think the problem is the :07 line.

I can not find Vesktop using zypper so I guess you installed it as Appimage.

As an experiment I would uninstall it and see if you can reproduce the problem.

19

vesktop is installed as RPM from here GitHub - Vencord/Vesktop: Vesktop is a custom Discord App aiming to give you better performance and improve linux support ,it’s just a discord client

it’s just the RPC plugin detecting blender cause i’ve installed an RPC plugin for it, yet even if in kill all instances of vesktop and start blender the exact same issue happens, i don’t believe it has anything to do with vesktop, i might be wrong but i don’t see the connection here

journalctl simply shows vesktop RPC detecting blender

From [Solved] Pipewire cuts out frequently but randomly and needs a restart:

Maybe Discord is the problem?

Always.

That page lists more debug options.
