Public bug reported: I have an ALC268 sound chipset (Santa Rosa platform) in my laptop (a Znote 6625WD) and just did a clean reinstall of Gutsy to get rid of some problems. Before I did the reinstall I had sound, albeit with some quirks (like the integrated speakers not muting when I plugged in my external speakers), but now that I've reinstalled, I get no sound at all anymore. These are the steps I take to get sound:
I made a collection of 3 scripts to make getting sound in Gutsy easier. I did that in steps, and between steps I'd have to reboot: #Install the appropriate kernel headers sudo apt-get install linux-headers-`uname -r` echo "\nLinux headers installed.\n" #Get some prerequisite packages, at least I think they're still prerequisite for alsa 1.0.15 (they WERE for 1.0.14, at least) sudo apt-get install libncurses5 libncurses5-dbg libncurses5-dev build-essential ncurses-dev gettext echo "\nPrequisite packages installed.\n" #Extract the sources tar xjf alsa-driver-1.0.15.tar.bz2 tar xjf alsa-lib-1.0.15.tar.bz2 tar xjf alsa-utils-1.0.15.tar.bz2 echo "\nall alsa tar.bz2 files unpacked.\n" #Remove the /usr/src/alsa dir, if it exists sudo rm -r -f /usr/src/alsa echo "\n/usr/src/alsa removed.\n" #Make the dir alsa in /usr/src sudo mkdir /usr/src/alsa echo "\n/usr/src/alsa created.\n" #Move the extracted sources to /usr/src/alsa sudo mv ./alsa-driver-1.0.15 /usr/src/alsa echo "\nalsa-driver-1.0.15 moved.\n" sudo mv ./alsa-lib-1.0.15 /usr/src/alsa echo "\nalsa-lib-1.0.15 moved.\n" sudo mv ./alsa-utils-1.0.15 /usr/src/alsa echo "\nalsa-utils-1.0.15 moved.\n" #make alsa-driver-1.0.15 cd /usr/src/alsa/alsa-driver-1.0.15 sudo ./configure --with-cards=hda-intel echo "\nconfigured.\n" sudo make echo "\nmade.\n" sudo make install echo "\ninstalled.\n" cd .. #make alsa-lib-1.0.15 cd /usr/src/alsa/alsa-lib-1.0.15 sudo ./configure echo "\nconfigured.\n" sudo make echo "\nmade.\n" sudo make install echo "\ninstalled.\n" cd .. #make alsa-utils-1.0.15 cd /usr/src/alsa/alsa-utils-1.0.15 sudo ./configure echo "\nconfigured.\n" sudo make echo "\nmade.\n" sudo make install echo "\ninstalled.\n" cd .. Then reboot, then the 2nd script: #step 2 of the process. After this step you should reboot. sudo echo "options snd-hda-intel model=auto" >> /etc/modprobe.d/alsa-base echo "\n\"options snd-hda-intel model=auto\"\nadded to the end of\n\"/etc/modprobe.d/alsa-base\".\n" Then reboot again, then the 3rd script: #copy snd-hda-intel.ko to the right location sudo cp /lib/modules/2.6.22-14-generic/kernel/sound/pci/hda/snd-hda-intel.ko /lib/modules/2.6.22-14-generic/ubuntu/media/snd-hda-intel/ echo "\n/lib/modules/2.6.22-14-generic/kernel/sound/pci/hda/snd-hda-intel.ko\ncopied to\n/lib/modules/2.6.22-14-generic/ubuntu/media/snd-hda-intel/\n" #copy the needed kernel modules to the right location in /lib sudo cp /usr/src/alsa/alsa-driver-1.0.15/modules/* /lib/modules/2.6.22-14-generic/kernel/sound/ echo "/usr/src/alsa/alsa-driver-1.0.15/modules/* copied to /lib/modules/2.6.22-14-generic/kernel/sound/\n" #Run depmod to update modules.dep and map files sudo depmod -a echo "depmod -a run.\n" After that, reboot one last time. Steps 1 and 2 I got from the howto at https://help.ubuntu.com/community/HdaIntelSoundHowto and step 3 I got from http://ubuntuforums.org/showpost.php?p=3566719&postcount=8 I've (s you can see) already gotten a solution in the past, but for some reason that has stopped working. Any ideas anybody? ** Affects: ubuntu Importance: Undecided Status: New -- [Gutsy] alsa 1.0.15 not working on ALC268 https://bugs.launchpad.net/bugs/175204 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
