Webcam integrated microphone in dv6-3013nr

photoelectricgeek · 07-09-2011, 02:59 PM

Hello and thanks ahead of time for your help.

I'm running Ubuntu 11.04 on my HP dv6-3013nr that came with Windows 7 64-bit.(now it's simply a linux system)

Product Spec's from HP website

I was setting up google video chat and discovered that the internal webcam worked fine but the microphone either wasn't being recognized or wasn't receiving input for some reason. I tried recording in the default sound recorder app that comes with Ubuntu with the same result.

My first thought was to check the HP website for drivers, but in the specifications I saw that my laptop has a, "HP TrueVision Webcam with integrated digital microphone," and there was nothing more than webcam drivers listed.

I'm not sure where to go from here, but I guess that's why I made a forum post; any ideas?

P.S. (The webcam runs perfectly fine regarding video)

Hi photoelectricgeek, Welcome to LQ. It's likely a matter of telling the software which device to use for recording or input. Please post the output from the following.

Code:

$ sudo cat /proc/asound/card0/codec#* | grep Codec
$ arecord -l

Good luck. ;-)

Sorry for the delayed response, I've been doing some stuff around the house and didn't get the notification but it's not a huge rush. No outstanding need for the mic just yet but I'd like to get it up and running.

Okay, looks like your mic is card 0, device 0. Can you record from any application?

Good luck. ;-)

Well I've tried recording in sound recorder and gmail's voice chat but I'll download audacity and see if it records.

EDIT: Audacity didn't work either. Still no sound.

Sounds (no pun intended) like your mic just isn't configured. Please post the output from the following.

Code:

$ cat /etc/modprobe.d/alsa-base.conf

What does alsamixer or any mixer say about the mic?

Good luck. ;-)

I would post the output but after running that code the mic worked.

Thanks for the help.

Glad you got it sorted.

Good luck. ;-)

weird.
The mic was working fine after I ran some of those things you told me to enter in Terminal but now after a system restart it's no longer recognizing the microphone in chrome or the sound recorders.

Here's the output to the last code you gave...

Try adding one of the following options to /etc/modprobe.d/alsa-base.conf

Code:

options snd-hda-intel model=ref
options snd-hda-intel model=auto
options snd-hda-intel model=hp

Add each option one at a time to see if any of those work. After each change, restart, the open alsamixer and see what's working. If any of these work, you can stop there.

Good luck. ;-)
