Hallo!
My laptop is Fujitsu-Siemens AMILO Pa 2510 with an 64-bit processor.
My operating system is Ubuntu 7.10
My problem is that I can't make my headphones to work. When I boot to windows everything is ok.

A major problem with Linux is that new equipment can come with unsupported hardware, and sound and wireless are the top problem areas. If your laptop has a reasonably new sound chip, then it is likely that the ALSA developers have not yet been able to provide support for it. It can take up to 12 months from the time of first appearance of a new sound chip until the distros have support for it. As chip manufacturers normally only support Windows, us Linux users are left in the ***. I have just been through dealing with this problem on a new motherboard. It sounds however that you have sound working but just not with the headphones. In such a case it may be that you need to set suitable options in your /etc/modprobe.conf file.

You need to determine the sound chip being used. This should be somewhere in the output of dmesg. Alternatively run alsamixer and you should see what Linux detected as the sound card. It will also show the various volume controls and settings (gnome volume applet is a nicer looking alternative). You may note simply that headphones have been muted.

Then look for the Alsa documentation to see what options are available for the particular chip you have. Try some of the different options.

With Ubuntu it is actually quite easy to install the latest ALSA drivers which may contain additional support. Ubuntu currently has version 1.0.14 while the latest release is 1.0.15. My sound chip was supported therein. However try to avoid this as it can hose your installation if not done correctly.

Yes! That's my exact problem. My sound is working perfectly but not with the headphones. Although I plug in the headphones, it continuous playing the sound from the speakers.

The alsamixer command gave me this:
Card: HDA ATI SB
Chip: Realtek ALC883
Item: Headphone [dB gain=0.00, 0.00]

I don't know if this sound chip is a new one. The AlsaMixer shows me that the volume of the headphones are set to 100%.
The file modprode.conf doesn't excist. In the /etc directory there is only a subfolder with this name and specially it is called modprobe.d

How can I update the current version (1.0.14) to the latest release (1.0.15.)??

Thanks for your help!!

Great! The information needed should be given in [http://www.mjmwired.net/kernel/Docum...iguration.txt], however this does not mention your chip. It is out of date, so I will talk more about a recent version below. The change log for alsa-1.0.15 [http://www.alsa-project.org/main/ind....0.14_v1.0.15] mentions the chip a number of times, so there is support for it in this latest release.

There is a bug filed under https://bugs.launchpad.net/ubuntu/+s...er/+bug/114053. It appears that a number of people have your problem and have not been able to fix it yet.

Given the lack of success shown in the above bug discussion, you may prefer to wait before doing this. However there is quite a bit of support for the ALC883 under alsa-1.0.15. To install it, see the thread:

[http://www.linuxquestions.org/questi...oblem-596862/]

You'll see we had a little trouble initially but eventually got it to work OK, so you should look towards the end of that discussion.

If the problem is not overcome after a reboot, then you can try some options. Without the options statement, Alsa tries to get information from the BIOS, which may not always work properly. In the process of installation you will have untarred the file alsa-driver-1.0.15.tar.bz2. Go to the directory alsa-driver-1.0.15/alsa-kernel/Documentation/ and open the file ALSA-Configuration.txt. Look for the section mentioning the ALC883. You will find all the options listed there, which refer to different configurations for various machines and cards.

The module options file needed under Ubuntu is /etc/modprobe.d/alsa-base (modprobe.conf is a RedHat file, I'm still weaning myself away from Fedora). At the end of this file, try adding:

options snd-hda-intel model=3stack-dig

and reboot. Then see what you get in alsamixer. If it doesn't work, try other options mentioned in above ALSA-configuration.txt.

I found solution that works with Amilo Pro (Fujitsu - Siemens).

You have to add 2 lines to your /etc/modprobe.d/alsa-base file

#add this lines
options snd-hda-intel model=3stack enable=yes
options snd-hda-intel model=auto position_fix=1 enable=yes


and restart laptop. I hope it helps.

Oreja thanks for the help. You are close enough. With this two lines I managed to hear sound from headphones. But the problem is still there. The sound is coming from the speakers too. I would like to mute the speakers when I plug-in the headphones and enable them back when I unplug them.

Thanks and sorry for my english level.

I upgraded to Ubuntu 8.04 and now the alsa-base is version 1.0.16.
I added again the lines that oreja gave me but the problem haven't been solved yet.

According to the bug report https://bugs.launchpad.net/ubuntu/+s...er/+bug/114053, the problem hasn't yet been solved. A bit disappointing.

my sound setup is
Card: HDA VIA VT82xx │Chip: Analog Devices AD1986A │View: [Playback] Capture All │Item: Headphone [dB gain=-21.00, -21.00]

#add this lines
options snd-hda-intel model=3stack enable=yes
options snd-hda-intel model=auto position_fix=1 enable=yes

added alot of sound support to my box.

Thanks again

The problem is still there...
Any solution?

well i've heard that on some machines with linux headphones only work if they are connected before the system boots. try doing that.

Debian Development

I have upgraded to ubuntu 9.04 and the problem is still there after so many years!

A solution is to add the line:
options snd-hda-intel model=acer

at the end of the file /etc/modprobe.d/alsa-base.conf

This can mute the laptop speakers at all. It's a little bit better but not a clean solution.

I added the line "options snd-hda-intel model=targa-2ch-dig" to the file "/etc/modprobe.d/alsa-base.conf".

Now, headphones and speakers share the same volume control.
You get a separate separate window called "Switches" (in Dutch: "Schakelaars") in which you can enable/disable the headphones output. Only now, (in my case) the speakers are muted and cannot be unmuted/enabled, anymore.
I don't care about that, because I don't use sound unless I'm watching a movie or listening to a song, which I only intend to do by using the headphones.

My stuff:
Operating System: Ubuntu Jaunty Jackalope 9.04 AMD64
Computer: Fujitsu-Siemens Amilo Pa1510 (AMD64 processor)
Audio device: ATI Technologies Inc IXP SB4x0 High Definition Audio Controller (Realtek ALC883)

p.s.:

- you might wanna have a look at: https://bugs.launchpad.net/ubuntu/+s...2?comments=all
- In my case the following lines did not resolve anything:
options snd-hda-intel model=3stack enable=yes
options snd-hda-intel model=auto position_fix=1 enable=yes

This problem fixed by newer versions of Ubuntu Linux.
