I resolved the problem by adding the following line to the /etc/modprobe.d/alsa-base:
options snd-hda-intel index=0 single_cmd=1 model=laptop-eapd Now the sound ALWAYS works, even without the boot option apci=off. -- Sound does not work WITHOUT apci=off command https://bugs.launchpad.net/bugs/117035 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
