Hi I have no sound since upgrade from 8.04 to 9.10 on a compaq Presario 1200 which worked perfectly prior to upgrade.
My sound card is: 00:07.5 Multimedia audio controller: VIA Technologies, Inc. VT82C686 AC97 Audio Controller (rev 20) I have also lost wireless and touchpad functionality which is another issue. I tried the extensive command line upgrade to ALSA 1.0.21 with no joy. Where do you go from here. Here is the process i tried: cat /proc/asound/version Advanced Linux Sound Architecture Driver Version 1.0.18rc3. To avoid problems during the upgrade of Alsa-utils, we need to stop it with the following command : sudo /etc/init.d/alsa-utils stop We must then install the necessary tools to compile along with the kernel headers : sudo apt-get -y install build-essential ncurses-dev gettext xmlto sudo apt-get -y install linux-headers-`uname -r` libncursesw5-dev Then, we go in our personal folder and download alsa-driver, alsa-lib and alsa-utils : cd ~ rm -rf ~/alsa* ~/.pulse* wget ftp://ftp.alsa-project.org/pub/driver/alsa-driver-1.0.21.tar.bz2 wget ftp://ftp.alsa-project.org/pub/lib/alsa-lib-1.0.21a.tar.bz2 wget ftp://ftp.alsa-project.org/pub/utils/alsa-utils-1.0.21.tar.bz2 After that, we create a new folder for the compilation and installation of the 3 files. Then, we move the 3 tar files that we just downloaded in this folder : sudo rm -rf /usr/src/alsa sudo mkdir -p /usr/src/alsa cd /usr/src/alsa sudo cp ~/alsa* . Unpack the 3 tar files : sudo tar xjf alsa-driver* sudo tar xjf alsa-lib* sudo tar xjf alsa-utils* We compile and install alsa-driver : cd alsa-driver* sudo ./configure sudo make sudo make install We compile and install alsa-lib : cd ../alsa-lib* sudo ./configure sudo make sudo make install We compile and install alsa-utils : cd ../alsa-utils* sudo ./configure sudo make sudo make install If like me, you got this error during the last “sudo ./configure” : checking form.h presence... yes checking for form.h... yes checking for new_panel in -lpanelw... no configure: error: panelw library not found I got the ERROR ¨file included in Linux/version.h does not exist. Install the package with full Kernal sources for your distribution¨ You will need to add those symbolics links (only if you got the error) and restart the installation from the last “sudo ./configure” : sudo ln -s libpanelw.so.5 /usr/lib/libpanelw.so sudo ln -s libformw.so.5 /usr/lib/libformw.so sudo ln -s libmenuw.so.5 /usr/lib/libmenuw.so sudo ln -s libncursesw.so.5 /lib/libncursesw.so Then, we remove the 3 tar files in our personal folder that are not anymore necessary : rm -f ~/alsa-driver* rm -f ~/alsa-lib* rm -f ~/alsa-utils* Then, just restart your computer and your alsa version should be 1.0.21! You can verify that you have now indeed have this version of alsa : cat /proc/asound/version Advanced Linux Sound Architecture Driver Version 1.0.21. Compiled on Aug 31 2009 for kernel 2.6.28-15-generic (SMP). Just to be sure everything is well configured, execute this command : sudo alsaconf I got file not found error on the alsoconf command!
