I am using kubuntu 19.09 and intel HD sound drivers with nvidia , was working perfectly.
I tried, ubuntu 20.04 live , my sound drivers was not working. So I thought there is driver issues with sound. today I updated my kubuntu and I have 2 kernels My sound drivers works, has no problem with kernel: 5.3.0-40 (good) Dumb Audio (no sound at all) in 5.3.0-45 (problem) Input : intel smart sound Technology TSS output : Realtek High Defination audio. So now in the boot of Grub, I choose advance, then old kernel.. Sound just works fine that way. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1869799 Title: no sound driver since 5.3.0.42 kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1869799/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
