#StackBounty: #drivers #sound #pulseaudio #dell #alsa Ubuntu 20.04 Dell Inspiron 3000 on-board audio not being detected

Bounty: 100

This is a fresh install of 20.04 on a Dell Inspiron 3000.

The system will detect an external headset and hdmi as an output/input, however, it will not detect the internal speakers/mic.

Any ideas on where to look next would be greatly appreciated, thanks.

#StackBounty: #sound #kernel #alsa #hdmi No HDMI audio device on intel_snd_hda (Ubuntu 20.04)

Bounty: 100

I have a home server that I want to use as a media server.

But when I connect to a TV, there is no sound.

I’ve tried to update to latest available kernel, and also switch kernel module snd-hda-intel to generic. This fixes issues with no sound device, and now 3.5 jack works, but still no HDMI.

#StackBounty: #sound #microphone #headphones #flatpak Flatpak apps do not detect headphone microphone

Bounty: 50

Flatpak apps such as Skype or Zoom do not detect my headphone microphone. If I start them with my headphones plugged in no microphone is detected, whereas if the headphones are unplugged the built-in microphone is detected. The headphone microphone does work elsewhere.

I tried running them with the --device=all argument but it doesn’t seem to make a difference.

How can I troubleshoot this?

#StackBounty: #sound #pulseaudio #alsa #headphones Headphone Sound Output Gets Mixed with the Line-Out Output

Bounty: 100

Problem Summary

When the line-out speaker is selected as the sound output, the sound
is fine. Sound comes only from the speakers connected to the line-out port. However, when the headphone is selected as the output device,
sound comes out both from the headphone and the speakers.

Details

My desktop computer has three sound output options:

  • HDMI/Display port (not used)
  • Headphone port at the front (headphone
    connected)
  • Line-out port at the back (speakers connected)

When line-out is selected as the output device, the sound is
heard only from the speakers connected to the line-out port. No problem there.

enter image description here

However, when headphone is selected as the output device, the sound is
heard both from headphones and the speakers connected to the line out
port.

enter image description here

This is really strange and beats the very purpose of the headphone,
namely, privacy and not disturbing others.

Current Settings

My sound card as found is as follows.

sudo aplay -l
**** List of PLAYBACK Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC3234 Analog [ALC3234 Analog]

rest snipped

I even tried setting the sound volume of the line-out to zero in
settings. This works for the line-out speakers. However, this does not
seem to have any effect on the sound volume when the headphone is
selected. The line-out speakers are equally loud, even with the sound volume set to zero.

enter image description here

I am not sure whether the output from alsamixer will be useful. But
here it goes anyway.

#StackBounty: #sound #pulseaudio #microphone #pavucontrol #usb-device Microphone not showing up as input device in settings, only in pa…

Bounty: 150

I have an audio interface, a UMC404HD, that I use both for my speakers and for my microphone. It’s plugged in via USB cable. This used to work under Ubuntu 20.10. However something seems to have gone wrong as I updated to 21.04.

The main problem is that I can’t select the interface as microphone input any more. The only available input is from my webcam, where previously it allowed me to select the UMC404HD as microphone as well:

Photo here, since you can't take screenshots of a drop-down

404 not found, as they say.

However the device is plugged-in and somehow working. Pavucontrol does show me the device and its volume levels:

Pavucontrol shows the device

These levels peak as I tap on the microphone. It’s actually getting input from it. But it’s somehow not allowing it to be chosen as a microphone. Note also that the "Port:" drop-down is missing from the UMC404HD device.

In the Configuration tab of Pavucontrol, the device is configured as output+input:
Analog Surround 4.0 Output + Multichannel Input

Do you know why the device is not available as microphone input?

#StackBounty: #drivers #sound #usb #multiple-monitors #hdmi screen not displaying with Startech hdmi to usb adapter

Bounty: 50

I bought a startech hdmi to usb adapter a few weeks ago.

I’ve installed the driver for my ubuntu, display was doing fine.

However, a few weeks later, the screen is now, not displaying any images.

Funny part is that the star tech adapter is recognized when I plugged it in and the strange thing is that the sound channel is using the startech adapter.

Not sure, what is wrong.

When I type xrandr, no additional HDMI plugin is seen.

This is the plugin I’m talking about.

I’ve done all the required updates through apt update.

If you have any ideas, I’m more than glad to hear them.

PS: I was thinking to have a look at the BIOS but not sure, what I should be looking for.

#StackBounty: #sound #pulseaudio #microphone #microsoft-teams #pipewire Pipewire is not recognized by MS Teams (but Pulseaudio is)

Bounty: 200

Recently I moved from Pulseaudio to Pipewire (Replacing Pulseaudio with Pipewire in Ubuntu 20.04)
Everything is working as expected except for Microsoft Teams desktop app (downloaded teams_1.4.00.7556_amd64.deb package from official Microsoft site): it’s showing no speakers or microphones available.
If I switch back to Pulseaudio, it works correctly.

I found a similar discussion here: https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/838#fromHistory
but I’m not able to apply the proposed solution (https://gitlab.freedesktop.org/pipewire/pipewire/-/issues/838#note_875806)

Bounty: 50

I bought a t.bone SC 420 USB Microphone.

Recording via Audacity works fine.

But as soon as the USB cable is connected to my PC, there is no more audio output.

I changed the settings, but nevertheless. The PC audio output is selected, but no sound is audible.

As soon as I unplug the USB cable of the microphone, audio output is audible again.
