    Exclamation Ubuntu 9.10 Acer8930G sound/surround sound

    Don't no where to start.
    I have an Acer 8930G Laptop.
    Testing Ubuntu 9.10 32bit
    Intel core 2 DUO (2.0GHz) T6400
    3GB Ram

    There is no stereo sound it is mono, if i move the balance slider left to right it moves the sound front to rear.
    if i select 5.1 surround sound will only come out of the LFE (Subwoofer).
    Any body got any ideas.

    I could never get the sound working right in 9.04.
    But for 9.10 you need right click on the volume (speaker icon next to the time),
    click on the hardware tab, at the bottom you should she a drop menu (Settings for selected device Profile (mine says alalog stereo duplex) click on it and select (analog Surround 5.1 Output + Analog Stereo Input) then select (Output tab) at the top).

    remember i am using acer 8930g this maybe different for each computer.

    Hi RiggUSA,
    The way you described, I got in Ubuntu 9.04. But, In ubuntu9.10 I am seeing any such options. Ubuntu 9.10 is not detecting my on-board sound chip RLC-883... Other than this all other features are good in Ubuntu 9.10. I tested, and happy with it. If I get this as well,. Will not think about going back to Ubuntu9.04..

    Sorry but i have no idea, I'm new to Linux, came over to Linux for the server side as i did not want to pay large amounts of money for basic server stuff, I jumped into to linux at the deep end, LOL.
    Then after seeing how stable it was I started installing it on all my computers, so yeah im learning, im hoping to get help with my sound problem too.

    I also have a Realtek 883 on-motherboard sound system. Sound worked on the Live CD of Karmic Koala (Ubuntu 9.10), but didn't when I installed. As a matter of fact, according to the System > Preferences > Sound, I didn't have any recognized hardware!!!

    I am stumbling around looking, but I have lost the link right now, but I found a suggestion to add a different user. According to the thread, a new user has a different set of defaults than the default user in a new setup. Guess what? Sound works on the new user. Now I have to decide if it is worthwhile to dig into what the differences between the different installs are.

    I have a 8940G and well setting up my sound I came on info that could help you. The newest version of Alsa specifically mentions the 8930G so I recommend updating to it (it is newer then the built in Ubuntu version)

    add this to your software sources "ppa:thefirstm/karmic-testing" then add "options snd-hda-intel model=acer-aspire-8930g" to /etc/modprobe.d/options then run update-manager and reboot after it is done

    it did not work, channels are still mixed up, only this time i got a high pitched noise from the speakers and when i was adjusting the balance it sounded like the speakers had lose wires.
    And no all hardware on the system is as perfect as can be.
