I have Mandriva One Spring 2007 Gnome installed on my presasio v6000.

Plugging in headphones does not divert the sound to the headphones, it still comes out the speakers.

There is nothing muted and cannot find any other configurations.

I have read about "headphone sense" but cannot find out what that is or where one might get it/configure it etc.

Any help?

Hi, I would have thought that was controlled by a switch built into the headphone socket. But that may

be an old fashioned way to switch.

I am an audio engineer and have had to maintain many different types of hardware, but not all.

You may need to clean it somehow without getting anything else damaged.

If it is just a dirty switch (you may be able to find out from the hardware manufacturer) I would try to

clean it with alcohol on a cotton stick, but a very small one to fit into the 1/8" socket.

Could be tricky, so take care if you choose to try that.

No, the machine is dual boot with winders and it works fine when booted that way.

My best guess is that it is controlled with software. This will be a bit of a kludg, but it may work.

If you use the KDE desktop start the Sound Mixer (Multimedia > Sound > Kmix in the menu system).

When you open the Mixer window, check that the headphone volume slider is not at 0%.

Check the Switches tab, you may have an option to turn on/off the headphone/speakers.

As I said, this is a kludge. It may also be possible that HP has Linux drivers for your laptop features (but not very likely). Check their WEB site.

If the headphones are switched by the soundcard driver or some other driver included with the Laptop (for Windows), it will be proprietary software and may not be available for use under Linux.

Good luck,

Yes, but I am using GNOME and the sound mixer does not show that option.

In the menu at the top of your screen, Go to System > Preferences > Volume Control. Open the Edit menu > Preferences. In the preferences menu you can configure the Gnome Volume Control to display the controls you need to access. You can check mark any options for the headphones, then in the switches tab, make suer the headphone lfe is chackmarked.

HTH,

Nope, it only shows Master, PCM, and Capture.

This means, I believe, that Gnome/Linux is having trouble with the sound card.

What I am hoping for is a solution/patch. Some kind of driver or something but cannot find any answer for this.

Hi, if that is all that is available perhaps the kernel module for your soundcard is not loaded.

Type lsmod to see if there is a reference to it.

Also lspci -v will show all the devices connected to the pci bus.

See how you go, regards Glenn

PS

And as stated, I get sound from my speakers, just not from the headphone jack

I read the following facts from your posts:

When running Windows, speaker sound is switched off when headphones are connected to the laptop.

When running Linux, speaker sound is not switched off when headphones are connected to the laptop.

Sound works through the speaker system in both Windows and Linux.


These facts lead me to the following conclusions:

A Linux sound driver is installed and working correctly because you get sound in Linux.

The sound switching function that cancels speaker sound when the headphones are connected is controlled in software that is separate from the sound card driver, and this software is proprietary (owned by HP).

HP has made this software available for Windows users (the default OS for your Presario v6000), but not for Linux users.

I did a Google search and found this thread on the Ubuntu forums. See reply number 9. If you do not suspend your laptop, this may be a partial fix ...

HTH,

I found by updating the alsa driver that it worked.
