How do I disable Intel sound power management, to test whether that is the problem? It worked ok before: early through halfway into Fedora 27 it worked just fine, then near the release of Fedora 28 is stopped working on Fedora 27. And it doesn't work properly on F28 either. Most of the time it doesn't work properly, but very rarely it works just fine after coming out of suspend. Hi Ferry, Booting with "snd_hda_intel.power_save=0" disables power saving, but it's currently configured to be off in Fedora 27 so I don't think that's it. Since it worked previously and is easy to reproduce, bisecting[0] the kernel should pin-point the problem. [0] https://docs.fedoraproject.org/quick-docs/en-US/kernel/troubleshooting.html#bisecting-the-kernel that is a bit too large a bisect. it worked under f27 but not so much under f28. it tends to work a bit better with the current kernel but I still can't put my finger on it when it fails and when not. and with the current kernel 4.16.15-300.fc28.x86_64 it's a lot worse again. now I can almost never get it to do the right thing. *********** MASS BUG UPDATE ************** We apologize for the inconvenience. There are a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 28 kernel bugs. Fedora 28 has now been rebased to 4.17.7-200.fc28. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you experience different issues, please open a new bug report for those. issue still present. I now have a trick. when a youtube video has the really low volume problem, then I pause it, start a different youtube video, and if it doesn't have the problem, then I unpause the first one that had the problem ( and now no longer has the problem) and then pause the second video I also have this issue, Lenovo T570 with latest Fedora 28 updates as of Aug 8th. My Lenovo X1 Carbon (1st gen) also has the same issue after changing from a linux mint install to fedora 28. We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 28 kernel bugs. Fedora 28 has now been rebased to 4.18.10-300.fc28. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 29, and are still experiencing this issue, please change the version to Fedora 29. If you experience different issues, please open a new bug report for those. alas, the issue is still present on f28, kernel-4.18.12-200.fc28.x86_64 Still present on f28, 4.18.16-200.fc28.x86_64 I am an Arch user who stumbled upon this bug. I can confirm the regression happened somewhere between 4.15.3 and 4.15.5; assuming that those versions match. I am willing to create a new partition and install Red Hat or Fedora on it, if it helps with debugging. Can you run alsa-info.sh and attach the results? In Fedora it's provided by alsa-utils, it's probably the same package in Arch. Created attachment 1508684 [details]
Output of alsa-info.sh on 4.15.3

Thanks Tim! I see a likely culprit in 4.15.5 (commit 61fcf8ece9b6b09450250c4ca40cc3b81a96a68d upstream). Can folks test https://koji.fedoraproject.org/koji/taskinfo?taskID=31144584 when it's done building to see if that "fixes" the problem? Tim, if you'd prefer to build a kernel for Arch rather than install Fedora, I'll attach the revert patch since it doesn't revert cleanly. Created attachment 1508938 [details]
Revert Thinkpad dock patch
Wow, this seems to work a lot better on my T570. Been testing out some youtube videos and sound seems to be ok again. Been 10 minutes though. I'll continue to run this kernel for a few days to see if it's really fixed. Thanks for testing that, Ferry. I just reverted a patch that I guessed caused the regression, so I'll still need to come up with a real fix. I may or may not get as far as that today, though. Okay, so I dug into this a little bit. The patch that caused the regression was to fix the mic and headphone jack[0] on the T470 dock (and it seems like the same dock works with the T570). Does anyone have a dock, and if so, does the headphone jack on it actually work? [0] https://bugzilla.kernel.org/show_bug.cgi?id=195161 Ferry, would you mind testing https://koji.fedoraproject.org/koji/taskinfo?taskID=31184179 as well? Thanks. will do this weekend ok, first test, with kernel 4.19.4-300.rhbz1554304.fc29.x86_64 (the first koji build): Thinkpad Ultra Dock 3.5mm audio out does NOT work, speakers just turn off when docking and turn back on again when undocking. second test, with kernel 4.19.5-300.bz1554304.fc29.x86_64 (the second koji build): sound is back to 'broken' state, but Thinkpad Ultra Dock 3.5mm audio out does work again. Going to uninstall this one Third time is (hopefully) the charm. Upstream has a potential fix, can folks test out https://koji.fedoraproject.org/koji/taskinfo?taskID=31218204 when it finishes?

That one seems to be really good: sound on my T570 works like it should and the audio out on the ultra dock also works as it should. docked and undocked a few times and works like a charm. I like that kernel. Finally the sound issue is fixed! Only took 9 months ;-) kernel-tools-4.19.7-200.fc28 kernel-headers-4.19.7-200.fc28 kernel-4.19.7-200.fc28 has been submitted as an update to Fedora 28. https://bodhi.fedoraproject.org/updates/FEDORA-2018-a0914af224 kernel-tools-4.19.7-300.fc29 kernel-headers-4.19.7-300.fc29 kernel-4.19.7-300.fc29 has been submitted as an update to Fedora 29. https://bodhi.fedoraproject.org/updates/FEDORA-2018-5904d0794d kernel-4.19.7-300.fc29, kernel-headers-4.19.7-300.fc29, kernel-tools-4.19.7-300.fc29 has been pushed to the Fedora 29 testing repository.
