Created attachment 1195868 [details] state of ALSA before the suspend Description of problem: When getting my laptop through suspend/resume cycle, the sound stops to work. Sound using applications (e.g., Firefox on YouTube, or totem) don’t look disturbed but no sound happens on the computer’s speakers. The workaround I found for getting the sound back is to flip on/off switch in the Sound applet of the Control Center. Attached is the output of the alsa-info.sh script before suspend, and after resume, while the sound was not working (and diff between the two). Version-Release number of selected component (if applicable): alsa-firmware-1.0.28-2.el7.noarch alsa-lib-1.1.1-1.el7.x86_64 alsa-lib-devel-1.1.1-1.el7.x86_64 alsa-plugins-pulseaudio-1.1.1-1.el7.x86_64 alsa-tools-firmware-1.1.0-1.el7.x86_64 alsa-utils-1.1.1-1.el7.x86_64 pulseaudio-6.0-8.el7.x86_64 pulseaudio-gdm-hooks-6.0-8.el7.x86_64 pulseaudio-libs-6.0-8.el7.x86_64 pulseaudio-libs-devel-6.0-8.el7.x86_64 pulseaudio-libs-glib2-6.0-8.el7.x86_64 pulseaudio-module-bluetooth-6.0-8.el7.x86_64 pulseaudio-module-x11-6.0-8.el7.x86_64 pulseaudio-module-zeroconf-6.0-8.el7.x86_64 pulseaudio-utils-6.0-8.el7.x86_64 How reproducible: Steps to Reproduce: 1. suspend/resume laptop 2. run a program producing sound 3.

I can see that too, I filed a bug than it went gone for a while but now it is back.

I'd also noticed one thing. Alsa or pulse are not able to detect headphone plugged in/out. Headphone output is always activate even if I try ti plug/unplug headphone jack several times. It means for me that the sound goes always to headphones and it doesn't if they are connected or not.

It means for me that the sound > goes always to headphones and it doesn't if they are connected or not. I've also experienced this. Is it worthy of a different bug report though? (some times in the rush to try and connect to video conference call on laptop you just work around the issue and I keep forgetting afterwards to investigate further). Cliff
This issue was fixed in kernel-3.10.0-498.el7 . Could you test ?
I rebooted to -500, I did the suspend/resume cycle several times and it seems the initial issue be gone. Will test the jack issue too.

Rebooting to new kernel *seems* to be working as expected from quick test of it. kernel-3.10.0-500.el7.x86_64 Thu 01 Sep 2016 13:48:46 BST kernel-3.10.0-495.el7.x86_64 Fri 26 Aug 2016 13:11:26 BST kernel-3.10.0-493.el7.x86_64 Fri 19 Aug 2016 20:00:07 BST
Suspend/resume with the kernel -500 works, but now (even with older kernels, but after yesterday's upgrade to the RHEL-7.3 Nightly) I got bug 1372427. :( This one bug however is fine.
