[Bug 1761051] Re: laptop sound broken in latest update -- "No output or input devices found"
Sound is not completely broken: With chromium-browser i can watch videos with sound on youtube.com, and on slack.com both speaker and microphone work. But using Firefox with the same web sites does not have any sound. The music players Amarok and Rhythmbox also do not produce sound, which makes me sad. I have not found one that works. Any suggestions as to where to start if i want to try and fix this myself? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1761051 Title: laptop sound broken in latest update -- "No output or input devices found" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1761051/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

OK, i'm now running the V4.16.0 kernel: > craigster0@p51:/local/home/craigster0/Downloads/linux-kernel-4.16$ uname -r > 4.16.0-041600-generic and clicking on the "speaker icon" on the menu bar at the bottom of the screen still shows "No output or input devices found". more importantly, trying to play audio with Amarok or Rhythmbox produces no audible signal. i also tried booting with the oldest kernel still installed on the box, vmlinuz-4.13.0-36-generic, which was installed well before this problem occurred and the sound still didn't work. to the best of my recollection. i don't think this problem was _caused_ by a kernel update. both speakers and microphone worked fine with all apps before i performed a software update, and failed after that. the trick is figuring out exactly which software update caused the problem! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1761051 Title: laptop sound broken in latest update -- "No output or input devices found" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1761051/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Yes, i should be able to test with the v4.16 kernel. I'll try to do that tonight.

[Bug 1761051] Re: laptop sound broken in latest update -- "No output or input devices found"
i'm wondering whether i should try rolling back to the previous kernel version. (i didn't notice any updates to sound drivers or software when i reviewed the packages to be upgraded, but i may have missed something.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1761051 Title: laptop sound broken in latest update -- "No output or input devices found" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1761051/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
