This is upstream problem I think. 

I have i5-6600 at Asus H110-C. lspci shows this: 

00:1f.3 Audio device: Intel Corporation Sunrise Point-H HD Audio (rev 31)
	Subsystem: ASUSTeK Computer Inc. Sunrise Point-H HD Audio
	Flags: bus master, fast devsel, latency 32, IRQ 124
	Memory at f7120000 (64-bit, non-prefetchable) [size=16K]
	Memory at f7100000 (64-bit, non-prefetchable) [size=64K]
	Capabilities: [50] Power Management version 3
	Capabilities: [60] MSI: Enable+ Count=1/1 Maskable- 64bit+
	Kernel driver in use: snd_hda_intel
	Kernel modules: snd_hda_intel

Error in dmesg is slightly different: 

[    1.146732] snd_hda_intel 0000:00:1f.3: bound 0000:00:02.0 (ops 0xffffffff818835f0)
[    1.260249] snd_hda_intel 0000:00:1f.3: CORB reset timeout#1, CORBRP = 0
[    1.261840] snd_hda_intel 0000:00:1f.3: no codecs found!

The problem occured after suspend (with pm-suspend). Everything worked ok before this, but now I can't get sound even after reboot to other Linux.

With kernel 4.3.3-301.fc23.x86_64, dmesg|grep snd:
