Configuring Headphones for Ubuntu 7.04 on a Toshiba A135-S2356

A user named Chris submitted a comment on my “Configuring Ubuntu 7.04 on a Toshiba A135-S2356” post that helped me fixed a problem on my laptop in which the headphones did not mute the external speakers. The sound card used by my Toshiba laptop is the ATI SB450 HDA. The steps to fix the headphone problem are below. Note, I did not have to use the realtek 6 patch that Chris mentions.

If you have the same laptop as me and the following instructions do not work, please post a comment.

  1. Download the latest ALSA source files from http://www.alsa-project.org. I’m not sure if you need all of these, but I downloaded the driver, lib, and utils packages. The versions I retrieved are 1.0.14, 1.0.14a, and 1.0.14, respectively.
  2. Next, compile the driver, lib, and utils packages, in that order. To compile package, perform the following commands from a command prompt:
    ./configure
    make
    sudo make install
  3. In my previous post “Configuring Ubuntu 7.04 on a Toshiba A135-S2356,” the instructions asked you to append
    options snd-hda-intel probe_mask=8 model=3stack

    to the file /etc/modprobe.d/alsa-base. Now, “3stack” needs to be changed to “lenovo”.

  4. Reboot.
  5. If you plug in the headphones, the external speakers will mute. However, if you adjust the “Front” volume in the system volume controls, the external speakers will unmute. Fortunately, you can do something about this. Launch gnome-volume-control, either by double clicking the volume icon on your task bar, or by running gnome-volume-control from a terminal. Set the “Front” volume at 100% and never touch it again. From here on out you can then adjust the volume by adjusting the “PCM” volume. The volume of many applications will be tie to the “Front” volume. Therefore, you should not adjust the volume through those applications. Instead use the “PCM” volume in gnome-volume-control.

  2. Thanks Ryan for this solution

  3. on 7.10 on amd64 with the latest alsa, I also had to move the existing snd-hda-intel.ko to old-snd-hda-intel.ko and run depmod.

  4. Somehow i missed the point. Probably lost in translation 🙂 Anyway … nice blog to visit.
