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: [ 4.056229] snd_hda_intel 0000:00:1f.3: bound 0000:00:02.0 (ops i915_audio_component_bind_ops [i915]) [ 7.082512] snd_hda_intel 0000:00:1f.3: azx_get_response timeout, switching to polling mode: last cmd=0x000f0000 [ 8.085170] snd_hda_intel 0000:00:1f.3: No response from codec, disabling MSI: last cmd=0x000f0000 [ 9.088809] snd_hda_intel 0000:00:1f.3: Codec #0 probe error; disabling it...
