I found the solution (!), create a new file /etc/modprobe.d/intel.conf add the following options:
options snd-hda-intel single_cmd=1 options snd-hda-intel probe_mask=1 This fixed my problem. Meanwhile when I restart, it has very strange cracking sound coming from laptop, not speakers. how can I fix this? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1542641 Title: PCI/internal sound card not detected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1542641/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
