Low Sound In Ubuntu 7.10 w/IFL90

I just reinstalled and dual booted Ubuntu, and now I have nearly no sound. At first I was puzzled, but then I recorded my voice with the sound recorder and played back, nothing from my laptop speakers. But when I hooked up my desktop speakers to my laptop's plugin, I could hear what I recorded but it is very very low. I checked all sound bars in alsa, everything is maxed to 100% sound.
I found out here that it's a bug, and that website provides a patch, but I am a linux noob, and need help. Here is the instructions:

Code:

Method E: Patch to add support for Realtek ALC268 Codec to Alsa 1.0.14

    *

      Does work: [WWW] Acer TravelMate 6292, Compal IFL90, MSI PR200, Extensa 5620
    *

      Does not work:

Support provided :

    *

      Internal speaker works
    *

      Headphones works (and internal speakers are automuted correctly)
    *

      External speaker works (and internal speakers are automuted correctly)
    *

      Internal mic doesn't seem to work...
    *

      External mic untested.

Procedure (See [WWW] #116326) :

    *

      Rebuild the linux-ubuntu-modules-2.6.22 packages after applying this [WWW] patch
      [B]Or use this already pacthed,ready to install, [WWW] linux-ubuntu-modules-2.6.22-14-generic_2.6.22-14.37.1_i386.deb.
      Note: It only works with an up-to-date Gutsy.[/B]
    *

      Add the following line in /etc/modprobe.d/alsa-base:

      options snd-hda-intel model=acer

      Note: You can specify one of the following model : acer, toshiba, 3stack or auto Note 2: For MSI PR200, use model=targa-dig
    *

      Reboot

The part in bold is what I did, I downloaded the .deb package and then ran it, to no avail. Please help.

 

I can help you with the part about adding that line to modprobe.

Open Terminal, and type or paste

Code:

sudo gedit /etc/modprobe.d/alsa/base

where the cursor is blinking. Tap the Enter key. You'll be prompted for your password. Type that in and hit Enter again.
A new window opens. The tab just above the text says "alsa-base".
Scroll down thru the text towards the bottom. Notice all the lines beginning with #? The # tells the operating system to ignore that line. The text behind each of those #'s was placed there for us humans to read and understand.

Not right at the bottom, but a few lines up, you'll see about a dozen lines that all start with the word "options". On my Acer 5920 there are ten lines. Simply place the cursor at the end of the last line in that group and tap "Enter" key. A new blank line is added, and the cursor jumps down to the beginning of this new line.

Type or paste

Code:

options snd-hda-intel model=acer

into that blank line, then go up to the "Save" icon and hit it. Then close the window. If you're feeling quite unsure about this command line stuff, go right back to the beginning. Open a terminal, do the "sudo gedit" command above, scroll down, see that you did indeed add the "snd-hda-intel model=acer" line to the group of "options" lines.

Good luck. I hope 8.04 solves most of these sound problems! My 5920 sound isn't quite right either.

 

For me, to get sound to work in Ubuntu with my IFL-90, I had to install the latest ALSA (version 15 something), and change the alsa-base file (as said in the post above me) to include

Code:

options snd-hda-intel model=toshiba

It would not work for me with anything else than toshiba as model.

A note though, the file to edit is /etc/modprobe.d/alsa-base, and not /etc/modprobe.d/alsa/base.
