    Help Needd! HP TX2500 no sound after upgrade to Ubuntu8.10

    Hi all,

    My leptop tx2500z lost sound when I upgradet my ubuntu system from 8.04 to 8.10. The sound was working good when I added a line in to /etc/modprobe.d/alsa-base:
    options snd-hda-intel index=0 model=toshiba position_fix=1

    When system boots to the login window, I heard big noise and it was gone after Desktop showed up. And then the OS totally kept silent. I can see the
    Volume Icon and also the sound card info.

    Can anybody help me? Thank you very much.

    I am having the same problemux. (A sickened former Vista user)
    after updating to 8.10. I didn't attempt the alsa-base edit yet, as I am new to Linux.

    If anyone has a solution, it would be greatly appreciated to give detailed steps for novices like me.

    Okay first just to make sure, upload your /etc/modprobe.d/alsa-bsse file for me to check....
    That line should work.
    You can also try the line:
    options snd-hda-intel index=0 model=acer

    Just now saw the other post...

    Okay, sound will not work without editing the alsa-base file.

    to do this simply:

    1. Press Alt+F2 this will open up a dialog.
    2. in the box, type
    Code:
    gksu gedit /etc/modprobe.d/alsa-base
    3. Scroll to the very bottom and add either one of these lines:
    options snd-hda-intel index=0 model=toshiba position_fix=1
    or
    options snd-hda-intel index=0 model=acer
    (you can only have one of these lines at a time, and the line needs to be on a line by itself)
    4.Now simply save this and restart.
    5. If sound does still not work, when you log in there should be a volume applet in the top-right corner of the screen. right click and select "Open Volume Control".
    6. I do not have your model of laptop, so You will have to play with the knobs, but it is pretty easy. Basically if a knob is muted or pulled down far, try maxing it out and see if you get sound.

    Thanks folks. I did added this line on my new 8.10 OS just like what I did on 8.04. The problem is in this new OS I only can hear big noise when I login.

    In my Volume Control I saw three options:
    HDA ATI SB (Alsa mixer)
    Realtek ALC268 (OSS Mixer)
    Capture:ALSA PCM on front:0 (ALCC268 Analog) via DMA .....

    The wired thing is that I installed a WinXP OS in my virtualbox and it has sound!

    I upload my alsa-base file below and hope some one would give me some advises.

    Does your sound work fine after that?

    I mean: I did it and I do have sound, but if I plug in my headphones, I still hear music from the speakers...

    P.S: I know this has been reported in other posts, I only want to understand if you did find a fix for it

    I am beginning to think it may be a problem with updating instead of installing a new os.... Some users say it works fine, while others are having the same error as you. Did you upgrade or reinstall?
