|
|
Hi everyone,
I want to use the microphone which is on my USB webcam :
Code: | root@laptop ~ # lsusb | grep -i cam
Bus 002 Device 003: ID 05a9:2640 OmniVision Technologies, Inc. OV2640 Webcam |
I have activated the kernel module for USB audio/midi :
Code: | Device Drivers --->
<*> Sound card support --->
<*> Advanced Linux Sound Architecture --->
[*] USB sound devices --->
<M> USB Audio/MIDI driver |
Only the video part of my webcam is currently working, because I have activated this on the kernel :
Code: | Device Drivers --->
Multimedia devices --->
<*> Video For Linux
[*] Enable Video For Linux API 1 (DEPRECATED)
[*] Video capture adapters --->
[*] V4L USB devices --->
<M> USB Video Class (UVC)
[*] UVC input events device support
<*> OmniVision Camera Chip support |
So, I've got theses modules loaded :
Code: | root@laptop ~ # lsmod
Module Size Used by
snd_usb_audio 91280 0
snd_usb_lib 16384 1 snd_usb_audio
snd_rawmidi 20992 1 snd_usb_lib
acpi_cpufreq 9296 0
nvidia 8113016 30
ieee80211_crypt_tkip 9280 0
wl 1262624 0
uvcvideo 54216 0
thermal 19232 0
processor 45048 4 acpi_cpufreq,thermal
button 7712 0 |
I have added this to my /etc/modprobe.d/alsa.conf :
Code: | alias snd-card-1 snd-usb-audio
alias sound-slot-1 snd-card-1
options snd-usb-audio index=1
# Set this to the correct number of cards.
options snd cards_limit=2 |
I have also run update-modules, rebooted my computer or alsasound.
But I couldn't get my webcam's microphone working. It seems that the microphone is not even detected :
Code: | root@laptop ~ # arecord --list-devices
**** List of CAPTURE Hardware Devices ****
card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog]

Discard all samples (playback) or generate zero samples (capture) |

Any ideas ?

Yuu,
Your Englisg is much better than my French, so lets stick to English.
In /dev/snd you should have one controlCX when X is a digit for each sound card.
If thats there try and to see the controls on your two sound cards. One of them should only have a single slider - thats your webcam. _________________ Regards,

Thank you for your fast reply NeddySeagoon
It seems that I have only one controlC in /dev/snd :
Code: | root@laptop ~ # ls /dev/snd
controlC0 hwC0D0 hwC0D1 pcmC0D0c pcmC0D0p pcmC0D1p seq timer |
For the control of my cards, "alsamixer -c 0" is working, but showing the same output as "alsamixer" without arguments.
So, i assume that alsamixer is displaying the information of the first soundcard when no arguments are given.
But with argument "-c 1", it seems that alsamixer cannot manage the "second card".. I mean the microphone's webcam.
Code: | root@laptop ~ # alsamixer -c 1
wrong -c argument '1'
|
I'm wondering why the microphone is not detected. Maybe a bad configuration ?
(PS : i have used this guide to only get video working) _________________ Main laptop : T8300 cpu | 200 GB hard drive | 2 GB of ram | 8600M GT | Gentoo x86_64

Yuu,
You have the /dev node missing for your webcam sound. Its not likely to be the USB subsystem as the video works.
Please post your entire /etc/modprobe.d/alsa.conf _________________ Regards,

Hi again,
Here is my /etc/modprobe.d/alsa.conf :
Code: | # Alsa kernel modules' configuration file.
# ALSA portion
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore
##
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
##
## ALSA portion
## alias snd-card-0 snd-interwave
## alias snd-card-1 snd-ens1371
## OSS/Free portion
## alias sound-slot-0 snd-card-0

Yuu,
You need to uncomment
Code: | ## alias sound-service-1-0 snd-mixer-oss
## alias sound-service-1-3 snd-pcm-oss
## alias sound-service-1-12 snd-pcm-oss | so you get the controls
and uncomment and fix ## alias snd-card-0 snd-interwave
## alias snd-card-1 snd-ens1371
for your two sound cards. The second one is already done further down the file here
Code: | alias snd-card-1 snd-usb-audio
alias sound-slot-1 snd-card-1 |
I don't think the Code: | options snd-usb-audio index=1 | is actually obeyed any more.
Sometimes snd-usb-audio loads before my real sound card, then sound doesn't work. After all, playing sounds via a webcam isn't very good. _________________ Regards,

Hmm.. It still does not work :/
I modified my /etc/modprobe.d/alsa.conf like this :
Code: | # Alsa kernel modules' configuration file.
# ALSA portion
alias char-major-116 snd
# OSS/Free portion
alias char-major-14 soundcore
##
## IMPORTANT:
## You need to customise this section for your specific sound card(s)
## and then run `update-modules' command.
## Read alsa-driver's INSTALL file in /usr/share/doc for more info.
##
## ALSA portion
## alias snd-card-0 snd-interwave
## alias snd-card-1 snd-ens1371
alias snd-card-0 snd-hda-intel
## OSS/Free portion
## alias sound-slot-0 snd-card-0
## alias sound-slot-1 snd-card-1
##
# OSS/Free portion - card #1
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-12 snd-pcm-oss
## OSS/Free portion - card #2
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-12 snd-pcm-oss
alias /dev/mixer snd-mixer-oss
alias /dev/dsp snd-pcm-oss
alias /dev/midi snd-seq-oss
alias snd-card-1 snd-usb-audio
alias sound-slot-1 snd-card-1
# Set this to the correct number of cards.
options snd cards_limit=2 |
Then, I did a "update-modules", recompiled my kernel to have the Intel HDA audio as module :
Code: | Device Drivers --->
<*> Sound card support --->
<*> Advanced Linux Sound Architecture --->
[*] PCI sound devices --->
<M> Intel HD Audio
[*] Build hwdep interface for HD-audio driver
[ ] Support digital beep via input layer
[*] Build Realtek HD-audio codec support
...etc |
Then, i rebooted with my new kernel and my new module:
Code: | root@laptop ~ # lsmod
Module Size Used by
snd_usb_audio 91280 0
snd_usb_lib 16384 1 snd_usb_audio
snd_rawmidi 21056 1 snd_usb_lib

snd_hwdep 8008 2 snd_usb_audio,snd_hda_intel
processor 45048 4 acpi_cpufreq,thermal
button 7712 0 |
There's still no microphone around there:
Code: | root@laptop ~ # arecord --list-devices
**** List of CAPTURE Hardware Devices ****
card 0: Intel [HDA Intel], device 0: STAC92xx Analog [STAC92xx Analog]

Yuu,
Please post your /proc/bus/usb/devices ... all of it. I would like to look at your USB device tree.
You can if you would like to see what I will see _________________ Regards,

Yuu,
I don't think the microphone is a part of the webcam.
Your /proc/bus/usb/devices shows that the webcam belongs entirely to
I suspect that your microphone is attached to the mic input of your normal sound card. Run alsamixer and press F4 to see only the capture controls. _________________ Regards,

Aww.. I'm sorry.
I was sure it was a part of my webcam, because the microphone is near the webcam's CMOS sensor.
Here is a capture of my capture controls in alsamixer : http://img525.imageshack.us/img525/6092/alsamixer.png
Now, I should learn how to configure my softwares to use the microphone...

Yuu,
Its an easy mistake to make - I've learned something too - I did not ask the questions in the right order.
Not to worry.
I can't read your image. Its far too small but I have an Intel-HDA so I expect its the same as mine. The mic is probably connected as Front Mic (the left capture control), so set that control up. Recording cannot mix sources so choose Front Mic from Sources, the rightmost conrol.
At the top left of alsamixer, you should see Code: | Item: Input Source [Front Mic] |
Now try a simple recording application, like Sound Recorder if you are a Gnome user. _________________ Regards,

Hmm, i have raise all the volume bars, but I have no sound yet.
Here is a capture from all "views" in alsamixer : http://img240.imageshack.us/img240/5323/screenshot2009101719551.png
And here is the "capture view" : http://img61.imageshack.us/img61/3500/screenshot2009101719582.png
For the source, I don't have "Item: Input Source [Front Mic]", I have only theses items in the capture view :
- Capture [dB gain=22.50, 22.50]
- Capture 1 [dB gain=13.50, 13.50]
- Digital [dB gain=30.00, 30.00]
- Input Source [Mic] (whith no bar)
- Input Source 1 [Mic] (whith no bar)
- Mux [dB gain=40.00, 40.00]
- Mux 1 [dB gain=40.00, 40.00]
And since I'm a Xfce user i only have arecord, aplay and Skype. For testing, I've used :
Code: | yuu@laptop ~ $ arecord -d 10 -f cd -t wav sample.wav
Recording WAVE 'sample.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo |
But when I try to read the file, I don't hear any sound from my speakers.
Code: | yuu@laptop ~ $ aplay sample.wav
Playing WAVE 'sample.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo |
PS : I don't hear my voice from skype test call too. _________________ Main laptop : T8300 cpu | 200 GB hard drive | 2 GB of ram | 8600M GT | Gentoo x86_64

Hi and thank you for your reply.
Unfortunately, I forgot to mark this topic as "[Solved]", because it's solved since about eight months ago.
Here is a screenshot of my working setup, if anyone has the same issue.

By the way, I think that one moderator/admin can close this subject _________________ Main laptop : T8300 cpu | 200 GB hard drive | 2 GB of ram | 8600M GT | Gentoo x86_64
