Now I wrote a script like this (short form): echo auto > /sys/devices/pci0000\:00/0000\:00\:1f.3/power/control echo 1 > /sys/devices/pci0000\:00/0000\:00\:1f.3/remove echo 1 > /sys/bus/pci/rescan
When I boot LINUX the script runs as root in a loop until the ALC892 is recognized. But the ALC892 is only recognized after I hear a crack from the speakers. Sometimes after 5 loops, sometimes after very many loops, sometimes never. Always after a crack. It doesn't matter whether the laptop runs on a battery or a charger. Meanwhile, I believe that the problem has nothing to do with ALSA or PULSEAUDIO. I think there is a problem with the pci scanning in conjunction with ACPI or PCI-Power-Management. Maybe PM-UTILS too. But that's for experts. I am not familiar with kernel drivers. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1890869 Title: [Clevo N350TW with Intel Corporation Cannon Lake PCH cAVS] no sound from speakers and headphones To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1890869/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
