HP 6730b microphone not working (snd_hda_intel)

Sound works perfectly, but I just can't get the internal microphone to work, anyone had any luck with it?

I have the same computer.

What I had to do was to enable Capture in gnome-volume-control under preferences. A new tab should appear, and you can un-mute the capture device there.

I've tested it with Sound Recorder and Skype, and I haven't had any trouble so far.

Hope this helps

Unfortunately, no luck with unmuting the Capture device What else do you have unmuted? Maybe I'm missing something obvious.

And i added "options snd-hda-intel model=laptop" in my modprobe.conf since i had some problems with the sound, but it should only fix things

Are you sure that "laptop" is the right option for your laptop? Which sound chip is built in your laptop?

ls -l /sys/module/snd/holders

Have you tried setting the model option to "hp" ?

I don't think I have, no, I'll try it definitely. Here are the contents of /sys/module/snd/holders:

lrwxrwxrwx 1 root root 0 2009-12-01 14:06 snd_hda_codec -> ../../snd_hda_codec/
lrwxrwxrwx 1 root root 0 2009-12-01 14:06 snd_hda_codec_analog -> ../../snd_hda_codec_analog/

You could also try to modprobe the following modules:

snd-intel8x0 ; modprobe snd-pcm-oss ; modprobe snd-mixer-oss ; modprobe snd-seq-oss

This is taken from the ALSA Wiki(http://www.alsa-project.org/main/index.php/Matrix:Module-intel8x0)

And these are the model options available for the AD1981 soundchip:

AD1981
=====
basic        3-jack (default)
hp                HP nx6320
thinkpad    Lenovo Thinkpad T60/X60/Z60
toshiba    Toshiba U205

So you shpuld first try the "hp" model option.

Re: HP 6730b microphone not working (snd_hda_intel)

Has anyone found a solution to this?

I have a similar laptop and the exact same audio controller. Microphone hasn't worked on Mint7-x64 or Arch64 yet, but it did on Fedora 12. Seeing as Fedora uses Pulseaudio, I'll try getting that working on my laptop and report back.

edit:
Tried this (http://bbs.archlinux.org/viewtopic.php?id=84948), but the only noise that's recorded is a slight buzz which lasts for less than a second and then stops.

edit:
Updated to the latest kernel (2.6.32.2-2) and it all works well now.
