HP dv6000 Laptop : MIC on fedora 7 not working but the playback is absolutely fine
 

Hello Sir ,

I am using HP dv 6000 laptop and have got Fedora 7 installed .

Laptop inbuilt MIC not works & also the headphone-speaker toggle not works.

Soundcard works fine .
Vendor : Intel
Model : 82801G (ICH7 Family) High Definition Audio Controller

PCM Device is CONEXANT Analog .

I am using GNOME and GNOME/GStreamer-based Volume Control 2.18.0 .

I tried all possible preferences of volume controller(like enable/disable capture or line in or IEC958 etc.) but when I use my Skype(2.0.0.72) to test recording i am unable to hear anything what i recorded.

I have even tried the option for Enable Software Sound Mixing in System->Preferences->Hardware->Sound .

My aplay and arecord are also not working .

Do a "lspci | grep 'snd'" and see what it says. If you don't see something like "snd-hd-intel" you have the wrong driver running: this isn't an
AC'97 device.

Hello Sir ,

After using your advice i got absolutely no output from command :
-----------------------
# lspci | grep 'snd'
#
-----------------------

So sir do i have a wrong driver running. If so whats the way out ??

Thanks in advance .

I guess I was kinda tired when I wrote that: if I understand your original message correctly, you can play sound but not record it, right?

If THAT's the case, that's definitely a tough problem. I'm assuming it was working under windows.

Assuming you're not afraid to do it, compiling a new kernel from recent sources may be your best idea as there may have been a bug in the Intel HD driver when your current kernel was released.

Also proving how tired I was: the correct command I should have given you is "lsmod | grep 'snd'" --that is, list modules not list PCI bus. My bad.

If THAT doesn't work, and just entering "lsmod" shows nothing that looks like sound stuff, then your drivers aren't loaded. There's a chance your sound drivers are compiled into the kernel, but I don't think there are any distributions left that do that--having nothing at all appear when you run "lsmod" by itself, however, would make that highly suspect. You should only ever see that on old distro versions or non-stock kernels.
