    Re: No sound

    Try this

    echo "options snd-hda-intel model=asus" | sudo tee -a /etc/modprobe.d/alsa-base.conf
    if that doesnt work..and hopefully it will.
    be sure to gedit /etc/modprobe.d/alsa-base.conf

    and remove that added line.
    hope this helps

    Re: No sound

    I ran the command, it added the line, I restarted my pc, but it still didn't work. I wonder what the problem is.

    Its odd that everything else seems to work except the headphones and they do
    work with windows. Lets take a peek at the trigger bit and see if its zero'd out.

    Re: No sound

    try this.

    first gedit /etc/modprobe.d/alsa-base.conf
    then replace
    options snd-hda-intel model=asus
    with
    options snd-hda-intel model=m4a785td-v position_fix=0

    your machine must be fairly new as your chipset was not on this list


    http://doc.ubuntu-fr.org/audio_intel_hda#acer

    so you may have to experiment and change the model= "X"
    go slow..be patient. and reboot after each attempt.

    In gnome alsamixer microphone is not muted, and I also changed the alsa configuration as you recommended, but still no luck. However I hear a little tick sound in my headphone at bootup, but later it is mute. (It's not a hardware problem, because it still works under windows)

    Re: No sound

    I think i see the problem. notice how every thing else is tag20..except HP
    HP is the headphone. change that to 20 instead of 21 and see if that fixes it.

    Re: No sound

    sorry about the jumbeled mess i posted..i copied and pasted some of your
    output and it strung it all together. I built a quick file from you last post
    of settings and then grep'd it for "tag values"

    Unsolicited: tag=20, enabled=1
    Unsolicited: tag=20, enabled=1
    Unsolicited: tag=20, enabled=1
    Unsolicited: tag=20, enabled=1
    Unsolicited: tag=21, enabled=1
    Unsolicited: tag=20, enabled=1
    Unsolicited: tag=20, enabled=1
    Unsolicited: tag=20, enabled=1
    this was the result...and the only tag 21 is the HP tag.
    this has been interesting...i hope this is the fix let me know.

    Re: No sound

    sorry about just now getting back to you...mem day and all..got busy.
    anyway. after looking at the settings in my system..im not so sure that 21 tag in yours is the problem. From all the research ive done on this..it seems to be an old bug..but only with 64bit not 32. and the fix was getting the correct model and position_fix=
    values correct. so before you attempt to change that tag value lets try a different
    fix= value..its going to be 0,1 or 2 so you will have to experiment..it should be currently
    set at 0.

    thus far you entered.

    1. #"options snd-hda-intel model=asus"#
    2. #"options snd-hda-intel model=m4a785td-v position_fix=0"#

    try to gedit /etc/modprobe.d/alsa-base.conf

    again and remove the first line...if its still there
    then change options snd-hda-intel model=m4a785td-v position_fix=0
    to: options snd-hda-intel model=auto position_fix=1

    reboot and test....if it doesnt work change it to fix=2
    you can also experiment and change the model to ..asus...m4a....785 and try each fix=
    value....0,1 or 2 with each model change. Its going to take a little time and may be a
    bit frustrating but there is no simple fix i can find...so be patient,take your time.
