Thanks for this update Ben. I have an Acer Aspire 4520 which has nVidia HDA card with Realtek ALC268 codec. Installing linux-backports-modules-generic solved my sound problem. Only thing is that I had to manually add this line at the bottom of /etc/modprobe.d/alsa-base to make the sound work: options snd-hda-intel model=acer
Perhaps this line can be added automatically, for better user experience. I'm hoping this will be included in the gutsy-updates, since it solves so many sound problems. -- [gutsy] no sound on Dell Latitude D630/D830/Inspiron 1300/Precision M4300/Vostro 1500/1700/Apple Aluminium iMac/Acer TM6292 pci id 8086:284b https://bugs.launchpad.net/bugs/131133 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
