How to fix when audio is heared both in headphone and inbuilt speaker of laptop
Hi,
I am having a strange problem in my laptop( Dell latitude 620). I have installed mandriva linux. Even if i connect headphones in the jack provided, the audio can be heared both in headphone and also through inbuilt speakers of the laptop. I am using AlsaMixer v1.0.9. please see the technical details below: [root@santhosh santhosh]# uname -a Linux santhosh 2.6.12-12mdksmp #1 SMP Fri Sep 9 17:43:23 CEST 2005 i686 Genuine Intel(R) CPU T2500 @ 2.00GHz unknown GNU/Linux [root@santhosh santhosh]# lsmod | grep snd snd_seq_dummy 3524 0 snd_seq_oss 33024 0 snd_seq_midi_event 6880 1 snd_seq_oss snd_seq 51504 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi_event snd_seq_device 7884 3 snd_seq_dummy,snd_seq_oss,snd_seq snd_pcm_oss 50368 0 snd_mixer_oss 17952 1 snd_pcm_oss snd_hda_intel 14752 1 snd_hda_codec 83872 1 snd_hda_intel snd_pcm 83812 3 snd_pcm_oss,snd_hda_intel,snd_hda_codec snd_timer 22596 2 snd_seq,snd_pcm snd_page_alloc 9384 2 snd_hda_intel,snd_pcm snd 48644 11 snd_seq_oss,snd_seq,snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_hda_intel,snd_hda_codec,snd_pcm,snd _timer soundcore 8256 1 snd [root@santhosh santhosh]# lspci 00:00.0 Host bridge: Intel Corporation Mobile Memory Controller Hub (rev 03) 00:02.0 VGA compatible controller: Intel Corporation Mobile Integrated Graphics Controller (rev 03) 00:02.1 Display controller: Intel Corporation Mobile Integrated Graphics Controller (rev 03) 00:1b.0 Class 0403: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01) 00:1c.0 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 1 (rev 01) 00:1c.1 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 2 (rev 01) 00:1c.2 PCI bridge: Intel Corporation 82801G (ICH7 Family) PCI Express Port 3 (rev 01) 00:1d.0 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI #1 (rev 01) 00:1d.1 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI #2 (rev 01) 00:1d.2 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI #3 (rev 01) 00:1d.3 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI #4 (rev 01) 00:1d.7 USB Controller: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corporation 82801 Mobile PCI Bridge (rev e1) 00:1f.0 ISA bridge: Intel Corporation 82801GBM (ICH7-M) LPC Interface Bridge (rev 01) 00:1f.2 IDE interface: Intel Corporation 82801GBM/GHM (ICH7 Family) Serial ATA Storage Controllers cc=IDE (rev 01) 00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 01) 03:01.0 CardBus bridge: O2 Micro, Inc.

First question I have is whether you're dual booting and having the same problems in windows. It sounds like a mechanical problem in the headphone jack which is supposed to interrupt the signal to the speakers.

Hi Mason,
Thanks for your reply.... We had totally bought 4 laptops with exactly same configuration. In two of the laptops we had installed Windows XP. In the other two we had installed Mandriva linux. The windows laptop doesn't have any problem like this. But the other two Linux laptops are having the same problem. We haven't installed dual operating system on any laptop... Regards, Santhosh |
The issue is not resolved yet.
Is there anybody to help me ???? |
Open up alsamixer, and look for an entry that simply says "Headphone" with no volume bar. If you scroll over to select it, the "Item" at the top should say something like "Headphone Jack Sense [Off]". You will want to press 'M' to enable this option (which isn't even offered as an option in Windows...).

Hi ciotog,
Thanks for your reply. I opened the alsamixer window by typing the command 'alsamixer' There I couldn't find any option as 'Headphone' The options listed are 1) Master 2) PCM 3) IEC958 4) Capture 5) Input Source Please correct me if i am wrong. Sorry, I tried to post the screen shot of that window as an image attachment. But i couldn't find any option for image attachment in this forum. |
Hmm... Maybe that option isn't offered for the driver for your card. Have you tried compiling the most recent version of alsa? Maybe it's been added since 1.0.9

I tried installing the latest verion. But i get the following error.
I dont know how to fix this.

Do you have the patch command?
Code:
which patchThe "--with-kernel" option isn't really required, it will be detected automatically in most situations. Do you have kernel source installed for your kernel? If not, you'll have to install it first: http://linuxfornewbies.org/forum/ind...opic,18.0.html |
Yes am not having the patch command in my system.
Where can i get it and how should i install it. |
You can get the patch rpm here:
http://fr.rpmfind.net/linux/rpm2html...hp?query=patch Of course if you don't have "patch" installed I wonder what else is missing... You could try installing 3rd party alsa rpms, for example from here: http://www.mde.djura.org/index2006.0.html |
Thanks ciotog,
I have installed the 'patch' package and the kernel source package for my kernel. The driver installed successfully but the problem persist again..... |
That's too bad... The notebook I have at work uses the atiixp driver and it has lots of different settings, including the "headphone sense". I wonder how hard it would be to implement such a thing with the hda-intel driver?
FWIW my home computer doesn't have the "headphone sense" option either. |
hi me too facing the same prob.i have hp 2002 tu.
|
Here is your answer http://www.fzu.cz/~kolorenc/d620/ as i thought, a kernel thing. hope it works for you.
