[Solved] Logitech C270 Webcam no sound
I have bought a new webcam. I have tried Cheese to see if it works. The video works but not the sound.
The webcam uses pulseaudio. So maybe pulseaudio is on mute. How to unmute it?
Another possibility is offered on an Ubuntupage:
All I had to do is sudo modprobe snd_usb_audio and the right device appeared. After that I had to unmute it and select it for the software I was using, yay!
But Ubuntu is not Bunsenlabs.
What to do?

So does the modprobe command have any effect or not? Because modprobing a kernel module that handles USB sound devices sounds like a very sensible solution.

No, it didn't work. I used the programs Cheese and Skype to test it.

Re: [Solved] Logitech C270 Webcam no sound
Hmm, it did work, but I had to put the sound-level a notch higher. Thank you for answering, CooKiECruNChEr43.

Re: [Solved] Logitech C270 Webcam no sound
To load the module automatically at boot, add a single line containing the name of the module to /etc/modules
sudo tee -a /etc/modules <<< "snd_usb_audio"See modules(5)

Hmm....I'm looking at my /etc/modules file currently and it's depressingly empty..So I'm assuming all of the mods I have loaded being doing an lsmod, are loaded from the running of udev which loads them dynamically probing my hardware correct? But if I wanted to tell udev to load something as well, I'd stick it in /etc/modules?

Re: [Solved] Logitech C270 Webcam no sound
The sound doesn't work now. I did the "sudo tee"-command as Head_on_a_Stick suggested. But now it doesn't work.
It is strange that the volume control (=pavucontrol) of Skype shows that the microphone reacts to sound. But when I do the test call, nothing can be heard.
In Cheese the sound doesn't work either.

Cookie, make sure when you're using pavucontrol, under Configuration you have for the profile: output + input since it's a webcam

Re: [Solved] Logitech C270 Webcam no sound
The volume control under Skype is pavucontrol. I also installed pavucontrol itself.
Like I said, the volume meter of pavucontrol shows that the microphone of the webcam reacts to sound.

Is the module loaded though?
If you run `modprobe` on the module, does that fix the sound?

Re: [Solved] Logitech C270 Webcam no sound
Well, I have found it. I did what you asked me to do, Head_on_a_Stick. snd_usb_audio is in etc/module and I did modprobe it. What it made it work was the fact that I checked the box "fallback" in the built-in pavucontrol in Skypem (the checkbox sucks otherwise I would have thought of it earlier). The webcam must be the fallback of all audio. That did the trick.
Now the audio in Skype works.
I will check whether or not I have to do the modprobe command first before I can use Skype properly. I will let you know.

Re: [Solved] Logitech C270 Webcam no sound
I don't have to do the sudo modprobe command every time I want to use Skype. But I have to press the checkbox of "fallback" in options/sound/input devices/webcam every time I want to use Skype.
Thank you again for your answers.
