HP Pavilion dv6184ea notebook problems with Intel 3945ABG WLan card and adjusting sound volume

[Jonas Kvinge]

Hi all,

I have a HP Pavilion dv6184 notebook, everything seem to be working but I have to do

modprobe -r ipw3945
modprobe ipw3945

After I reboot to get the WLan card up and running.

I'm using packages ipw3945d version 1.7.18-9
and ipw-firmware 7-10

that comes with SUSE 10.1.

Do I need upgrade the driver with the drivers from Intel's official site, it has packages ipw3945-1.1.0, ipw3945d-1.7.22, ipw3945-ucode-1.13.

I'm unsure whether to install them or not.

KNetworkManager does not automatically reconnect to my wireless network, but I have to press connect and enter the passphase each time.

The sound works but I cannot adjust the volume via the Volum Control (KMix), I tried to play DVD with xine and I could adjust the volume there.

What OS are you running? Fedora Core 5 has some "issues" with the mixer. Only root and the first user to log in can set the mixer. This is a "feature." I think they've crossed the line between "secure" and "paranoid." How hard is it to stick a dummy plug in the microphone jack?

Presumably this "feature" can be disabled on installation, but it doesn't always seem to work. Check your permissions on "/dev/mixer" to see who is allowed to access it.

For your WLAN card, you probably need to add the packages to "modules.config" or "modprobe.conf," but I'm not very familiar with the syntax. Personally, I'd simply stick the modprobe commands in a script that runs on boot.

Hello Steve,

Thanks for the reply.

I am using OpenSUSE Linux 10.1

I forgot to mention that I did enter the following in the modprobe.conf.local file:

jonas@notebook:~> cat /etc/modprobe.conf.local
#
# please add local extensions to this file
#

install ipw3945 /sbin/modprobe --ignore-install ipw3945 ; /sbin/ipw3945d --quiet
remove ipw3945 /sbin/ipw3945d --kill ; /sbin/modprobe -r --ignore-remove ipw3945

It did not seem to work.

I tried now to add the modprobe commands to the boot.conf file:

modprobe -r ipw3945
modprobe ipw3945

Now the WLan card will work automatically upon boot but it does not save my settings for WLan. I have to click to connect and enter the passphase each time. Do you know any solution to solve that?

I am the owner of the mixer:

jonas@notebook:~> ls -la /dev/mixer
crw-rw----+ 1 jonas audio 14, 0 2006-11-20 20:41 /dev/mixer

I can adjust the sound volume in programs such as Amarok and kaffeine, but I cannot use the Kmixer to adjust the volume for some reason.

I tested the headphones output and KMixer works when adjusting that output, but not the internal speakers. Maybe it is supposed to be that way, its just a minor problem anyhow.

Do you know if there exists a driver for the webcam?

Thanks again.

Hello again,

I just tested something new:

I cannot mute the sound for the speakers without muting the headphones. That's a major problem for me.

[Steve_160]

I'm not sure I can suggest much more about the WLAN card.

I do have another suggestion on the soundcard, though. Try "alsamixer" and play around with the settings. The new on-board soundchips have a lot of off-the-wall settings that kmix doesn't recognize. In particular, they have multiple PCM channels that sometimes bypass other settings such as "master."

Alsamixer is a text-based mixer; you'll have to bring it up in a console window. The odd channels show up at the far right. (use right-arrow to scroll.) Most of the ones I've seen are called "VIA DXS," others are "Sigmatel." It depends on the chipset.

Hi Steve,

I already tried the alsamixer, there is just two channels there, PCM and capture. They do the same as KMixer.

It's a 82801G sound chip, I did a quick search on google and found that there were ppl having similar problems, but not same like mine. I think the problem is in the alsa library.

I will try some of the solutions found in the other forums, just need to backup the system first in case I mess it up
