Acer laptop: Sound not working

[yurukov]

I just got an Acer Aspire 1640Z. Here is the hardware: Pentium M 735A 1.7GHz (1.7GHz/2MB L2/FSB533); Intel 915GM Express chipset; DDR II 512MB; 15.4" WXGA Acer CrystalBrite; Video 64MB shared; Intel graphics Media Accelerator 900; 80GB; DVD-RW Dual DL ...

I installed Kubuntu 6.06 but one of my problems is that the sound is not working at all. I don't know what drivers should I download and how should I install them.

Anyone with any idea?

Try:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install --reinstall linux-restricted-modules-386 alsa-base libxine-extracodecs

Maybe you've already tried that, but if not, it's a good start.  Let us know if it works.

ronware submitted this as an official bug in ALSA:

We'll have to wait & see on this one.  Sorry I couldn't be of more help.

Re: Acer laptop: Sound not working

do "sudo lsmod" to see what sound drivers are loaded. check that there's one matching your chipset.

look at the files in /proc/asound/card0 to see what device is being assigned as the default - it may have the wrong one..

Check the file /etc/modprobe.d/alsa-base. The default install has some lines at the end with "option snd-driver index=-2". Change snd-driver to the desired driver, and the -2 to 0

You don't need sudo on the command that alpreston suggested but you REALLY, REALLY need "lsmod | grep snd", as you may have discovered if you ran the command.
