** Description changed: + The patch is already in the v5.2-rc1, so don't send the patch + to unstable. + + In the V2, I added 3 more patches. The 0001-xxx.patch is for fixing + the issue of "audio doesn't work after s3/s4 on cln and glk machines", + but it introduces a new issue of "screen flickering when CDCLK changes", + So I added 0002/3/4-xxx.patch to fix the new issue. + [Impact] After s3 or s4, the hdmi audio driver will re-probe the hw, if the hdmi monitor is not plugged before s3 or s4, the re-probe will fail on cnl and glk machines. [Fix] Keep the cdclk alive when re-probing [Test Case] - do s3 and s4 without hdmi monitor plugged, after s3 or s4, plug the hdmi - monitor, to check if the hdmi audio works well, it works well indeed. + I applied the patches to bionic kernel and disco kernel, and tested them + on Whiskeylake, cannonlake, kabylake, skylake and geminilake + machines, before s3, I verified analogue audio, hdmi audio and screen + dispaly all worked well, then let the system enter s3 and resume, recheck + the analogue audio, hdmi audio and screen display, all worked well too. + And repeated the test 5 times. + [Regression Risk] - Low. the 1st patch is specific to cnl and glk machines, and without this patch, - the cdclk is 0, after applying this patch, if hdmi audio want to probe hw, the - patch just set the a non-zero freq on cdclk. + Low. I have tested the patched kernel on different Dell and Lenovo machines, + they include Whiskeylake, cannonlake, kabylake, skylake and geminilake. - - When I close my laptop, it goes to sleep. When I wake it up, it switches to " headphones ". Then, if I go to " sound device ", my main speaker does not show. There's only the headphones that are here. I can't get my speakers back... I had to reboot the computer to get my device back. dmesg -w shows the following: snd_hda_codec_realtek hdaudioC0D0: out of range cmd 0:20:400:ffffffff snd_hda_codec_realtek hdaudioC0D0: Unable to sync register 0x2b8000. -5 ProblemType: Bug DistroRelease: Ubuntu 19.04 Package: linux-image-5.0.0-13-generic 5.0.0-13.14 ProcVersionSignature: Ubuntu 5.0.0-13.14-generic 5.0.6 Uname: Linux 5.0.0-13-generic x86_64 ApportVersion: 2.20.10-0ubuntu27 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: rob 1551 F.... pulseaudio CurrentDesktop: ubuntu:GNOME Date: Mon Apr 29 21:22:18 2019 InstallationDate: Installed on 2019-04-24 (4 days ago) InstallationMedia: Ubuntu 19.04 "Disco Dingo" - Release amd64 (20190416) Lsusb: Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 003: ID 05c8:022a Cheng Uei Precision Industry Co., Ltd (Foxlink) Bus 001 Device 002: ID 0bda:b00b Realtek Semiconductor Corp.
