Posted: Fri Jan 15, 2016 5:44 am Post subject: Please help me get my webcam mic working (PulseAudio/ALSA).

I have a Logitech, Inc. QuickCam Pro 4000

Code:

Bus 006 Device 005: ID 046d:08b2 Logitech, Inc. QuickCam Pro 4000

It is found by ALSA:

Code:

$ arecord -l
**** List of CAPTURE Hardware Devices ****
card 1: Generic [HD-Audio Generic], device 0: VT1708S Analog [VT1708S Analog]
Subdevices: 1/1
Subdevice #0: subdevice #0
card 2: U0x46d0x8b2 [USB Device 0x46d:0x8b2], device 0: USB Audio [USB Audio]
Subdevices: 1/1
Subdevice #0: subdevice #0
$ cat /proc/asound/cards
0 [Generic_1 ]: HDA-Intel - HD-Audio Generic
HD-Audio Generic at 0xfeb44000 irq 35
1 [Generic ]: HDA-Intel - HD-Audio Generic
HD-Audio Generic at 0xfeb40000 irq 16
2 [U0x46d0x8b2 ]: USB-Audio - USB Device 0x46d:0x8b2
USB Device 0x46d:0x8b2 at usb-0000:00:10.0-1, full speed

When I use the Mate Volume Control, I cannot unmute the mic. I click on unmute, but when I go back to the same dialog, it is muted again.

The USB device does not show up in pavucontrol (Input Devices).

I have re-started alsasound.

Any ideas?

I am not sure if this helps. Sometimes after upgrade I have problem with Skype ( the only application when using mic and webcam). Googling around I found this

Code:

Open Pulse Audio volume control.
Go to the 'Recording' tab. (This will be empty apart from the message "no application is
currently recording audio").
Open Skype and make a test call.
Skype will appear on the Recording tab of the volume control.
Click on the current "Input from..." option and select the one you want from the list.
Job done!

After that Skype works again

Thanks for the suggestion. I tried it, but the webcam mic still did not appear in the list of recording devices in the pavucontrol window.

I dont see mic too. In my case list of recording devices looks like that:
- Monitor ...
- Build-in audio ...
- Camera Analog Mono
Correct choice is the third one.
And one question. Which card do you have enabled in alsamixer?

I see the webcam input in alsamixer, but how do I enable it and save the settings?

Enable PulseAudio as soundcard in alsamixer. If you dont see PulseAudio option after pressing F6, select

Code:

It won't help I am affraid.
PulseAudio is a proxy for your sound applications. It passes data between your application and your hardware. It is strange, that you don't see PA in alsamixer.
Please run as normal user

Code:

cat /proc/asound/cards

detects three cards and

Code:

pactl list

only two. You should see something like that

Could you send output of

Code:

cat /usr/src/linux/.config|grep SND_USB

I think that would be better snd_usb_audio build in

Code:

CONFIG_SND_USB_AUDIO=y

Lets make another one mic test. As normal user run

Code:

arecord /tmp/test.wav

It will record indefinitely until ctrl+c is not pressed. Durig this time run pavucontrol, enter 'Recording' tab. You will see ALSA plug-in: ALSA Capture from ... and list of options. In the options should be

Quote:

Camera Analog Mono

Select this option and say something. After that open /tmp/test,wav with your favorit software player, e.g.

Quote:

mplayer /tmp/test.wav

and you will hear your voice

If not, your module is not loaded correctly.

I don't see Camera Analog Mono in the list. I have a screenshot, but I don't see any way to attach it to the post. In the list are:

Code:

Monitor of Built-in Audio Analog Stereo
* Built-in Audio Analog Stereo
Monitor of Built-in Audio Digital Stereo (HDMI)

IMHO it means, that module snd_usb_audio is not loaded. I suggest to recompile kernel with

Code:

CONFIG_SND_USB_AUDIO=y

I'll try recompiling with SND_USB_AUDIO built-in instead of as a module, meanwhile, I just checked:

Code:

# lsmod | grep snd_usb
snd_usb_audio 115382 0
snd_usbmidi_lib 17004 1 snd_usb_audio

Add this to /etc/pulse/default.pa:

Code:

.nofail
load-module module-alsa-source device=hw:U0x46d0x8b2
.fail

Do I need to re-boot after this?

Would you mind explaining what this does? I see the hardware address of my webcam in there.
