    GOT IT WORKING! - No sound with Intel HDA - in anything

    Laptop's sound controller, as reported by lspci:

    Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 02)

    I have no sound what so ever, in anything. I've reviewed the Ubuntu bug reports, and this appears to be a known problem. Of course, sound works perfectly well when running M$ Vista.

    My question is, until the problem is resolved, has anyone come up with a workaround to get sound functioning?

    Can you post which model of your laptop is ?

      Re: No sound - in anything

      My desktop board has that same Intel HDA sound system, and it works fine. You may need to fiddle with the Kmixer -- I think it defaults to mute or something. I'll attach a screenshot of how it is currently set on mine.

        yes but according to the model there's many options to specify and maybe a compilation of alsa 1.0.14rc* is needed

          Model: Toshiba Satellite P105-S6147.

          On of the 'fixes' that I came across (Googling):

          http://lostechies.com/blogs/jason_me...isty-fawn.aspx

          It refers to adding the line "options snd-hda-intel model=auto" or "options snd-hda-intel model=3stack" to the alsa-base file then "Exit anything that might be playing sound or has to do with sound" before running "sudo rmmod snd_hda_intel" and "sudo modprobe snd_hda_intel" then rebooting.

          Some say that this worked for them. Others, that it did not. I've also checked the BIOS to see if my system has a BIOS setting for sound - it does not.

          I've looked at the KMixer, but I'll do so again with Dibl's screen shot to make sure the switches are set the same.

          This what my KMixer settings look like:

            Anticipating the question as to what modules associated with the Intel HDA sound card are complied in the kernal, this is the output of modinfo snd-hda-intel snd-pcm-oss snd-mixer-oss snd-seq-oss

            As you say you have the same sound system, and you have sound, did you have sound without having to do anything? I got my DVD fully functional in 7.04 today (posted the steps I took to do so), so the only thing I don't have is sound. I'd really like to get this fixed, so if you or anyone else can help me get this resolved, I'd be extremely greatfull.

              Re: WORKING! - No sound with Intel HDA - in anything

              Okay, just a few minutes ago, I got working sound. This is the log of things I did, in order, with the last entry being what resulted in working sound. I don't know of the preceding items can be 'undone' and still have sound - I'll test that a bit later and report.

              So, here is what I did:

              From http://www.linux-on-laptops.com/foru...ead.php?p=3553
              Simpler solution
              sudo cat "options snd-hda-intel model=3stack" >> /etc/modprobe.d/options
              sudo update-modules

              Step 1. Open a Root shell
              Step 2. Copy /etc/modprobe.d/options to /etc/modprobe.d/options_original.bak
              Step 3. Edit as Root /etc/modprobe.d/options and add: options snd-hda-intel model=3stack
              Step 4. Run update-modules
              Step 5. Reboot and check for sound

              Rebooted. Still no sound.

              From http://ubuntuforums.org/showthread.php?t=251877
              Modify /boot/grub/menu.list and add "acpi=off" to the end of each kernel line

              Rebooted. I have sound! Yeah!!!!!

                The following link may be informative for the more experienced Linux users. It explains the why, and how to fix, common ACPI problems affecting Linux.

                  Re: GOT IT WORKING! - No sound with Intel HDA - in anything

                  Okay, tested to see if removing the options snd-hda-intel model=3stack line from /etc/modprobe.d/options would adversely affect my working sound. It did not. I still have fully functioning sound. So, it seems that the 'fix' to getting sound working with the Intel HDA (at least for me) is to add acpi=off to the end of the kernel lines of /boot/grub/menu.list
