HP DV4-1212la built-in mic trouble

Hello Arch linux community

Short story, I bought a brand new HP dv4-1212la and after all the reading and typing I finally got my new Arch64 to work. But it didn't come flawless.
Here are my flaws.

1) I cannot get the built-in mic to work. Alsamixer shows me the laptop comes with HDA ATI SB card and the chip is a IDT 92HD71B7X (it's working with the snd-hda-intel module). I have read and tried many solutions in this forum with no success and I really need the mic to work and the only sounds I got from it is a big fuzz.

2) The second flaw I have to set acpi. I don't mind this one too much and I know this is not forum to post it, but can anyone tell me where I can get good and clean info to get it working??

Please help me! And thanks to all the people that will help!

I almost forgot it. lspci output for my sound device 01:05.1 Audio device: ATI Technologies Inc RS780 Azalia controller

Re: HP DV4-1212la built-in mic trouble

For the mic issue, try creating a file called:

/etc/modprobe.d/alsa.conf

Containing:

options snd-hda-intel model=hp-m4

The hp-m4 model fixed the mic on my hp dv5t. Not sure if that's what will work for you. If it doesn't work, try some other models. Perhaps model=hp-dv5 would be another good bet.
See: http://www.mjmwired.net/kernel/Document … ls.txt#342 for the list of models.

You'll need to restart or reload your alsa modules after these changes.

Re: HP DV4-1212la built-in mic trouble

Statix, thank you but it didn't solved the problem. I tried "options snd-hda-intel model=hp-dv5" and it recorded very very fuzzy the playback of a youtube video, but it didn't record my voice or the clap of my hands gnome's sound recorder.

Anymore ideas about it???

Re: HP DV4-1212la built-in mic trouble

Problem solved. I've just had to change the model to model=dell-m4-1.

Now all the audio is working great. thanks statix, without your help I'd have not fixed my problem.

You can change the thread to 'Solved'.

Re: HP DV4-1212la built-in mic trouble

I've got an hp pavilion dv7 and though this works for me in xubuntu, it doesn't in arch :S

Here's what my modprobe.conf looks like:

#
# /etc/modprobe.d/modprobe.conf (for v2.6 kernels)
#
alias sound-slot-0 snd-hda-intel
alias snd-card-0 snd-hda-intel

options snd-hda-intel enable_msi=1 model=dell-m4-1
#options snd-hda-intel model=hp-dv5
#options snd-hda-intel model=hp-m4
#options snd-hda-intel enable_msi=1
options snd-hda-intel index=0
#options snd-pcsp index=1

And I'm turning it off and on like:

sudo /etc/rc.d/alsa stop && sudo modprobe -r snd-hda-intel
sudo modprobe snd-hda-intel && sudo /etc/rc.d/alsa start

When I make changes (which you can see by the .conf I've tried a bunch of stuff...

Any ideas? I'm testing with Audacity and not getting any mic input.
