Internal Microphone

S

Hi All,

I'm new to FreeBSD. I have a Dell XPS 15' laptop. It has a built-in webcam and microphone. I have heard that the support for webcam on FreeBSD is very primitive. I, however would like to configure my internal microphone which is not working now. Any help would be great. Thanks.

So your audio card is working (it doesn't show up as none, which means there is a driver). You can get your SD card reader working by loading mmcsd kernel module:
Code: 
# While running
kldload mmcsd
# To load at boot time
echo 'mmcsd_load="YES"' >> /boot/loader.conf

The iwn driver can be used for your wireless card, but it's experimental.

Can you show the output of the following 2 commands:
Code: 
mixer
cat /dev/sndstat
 
Hi Mel, Thanks for the quick response. Here are the required command outputs

Mixer

Mixer vol is currently set to 10:10
Mixer pcm is currently set to 100:100
Mixer speaker is currently set to 100:100
Mixer mic is currently set to 100:100

SNDSTAT

Sorry for the hold up. You're using a 2007 version for the HDA driver. I'm quite confident that upgrading to 7.1 or a -stable snapshot after Feb 26th this year, will fix your problem.
 
No success yet

Hi Mel,

I upgraded my system to FreeBSD 7.1. But even with this, the built-in microphone was not working. I then tried a fresh install of FreeBSD 7.1. But my microphone is still not working. Any other inputs required? Or any other suggestions? Thank you.
 
You can always ask on freebsd-multimedia mailing list. I'm sure that your sound card have multiple codec or whatever ....(I'm not HDA pro)

You need to update to 7 STABLE(it is now 7.2 PRERELEASE) and post pcm0 part of dmesg output again.
 
Hi Richard,

Thanks for replying. I had FreeBSD 7 earlier. I currently have FreeBSD 7.1 Release. Isn't that enough? Here are the required outputs

dmesg | grep pcm0

pcm0: [ITHREAD]

Hi All,

I have a Dell XPS M1530 laptop running FreeBSD 7.1 Release. I would like to know how I can get my built-in microphone working. At the moment, it isn't working. I hope the following details of my system would be useful

dmesg | grep pcm0

pcm0: <Intel 82801H High Definition Audio Controller> mem 0xfebfc000-0xfebfffff irq 21 at device 27.0 on pci0

Hi,

As can be seen from my earlier post, I was asked by one of the members to post this question in the multimedia section. I don't know which is the right section. Hardware section looks more appropriate to me. Anyway, please advise.
