Created attachment 108961 [details] alsa-info after resume Hi there, MacBook Air 6,2 Intel Core i7-4650U 1.7Ghz 8GB RAM 128GB SSD 3.12-rc1 I believe this is an ACPI issue but please advise if this is incorrect. There is no sound after resume from s3. Neither the cirrus logic codec nor the haswell HDMI are powered up. Reloading snd_hda_intel does not bring sound back. A complete restart is necessary. Below is the relevant section of alsa-info after resume: !!HDA-Intel Codec information !!--------------------------- --startcollapse-- Codec: Intel Haswell HDMI Address: 0 AFG Function Id: 0x1 (unsol 0) Vendor Id: 0x80862807 Subsystem Id: 0x80860101 Revision Id: 0x100000 No Modem Function Group found Default PCM: N/A Default Amp-In caps: N/A Default Amp-Out caps: N/A State of AFG node 0x01: Power: setting=UNKNOWN, actual=UNKNOWN, Er ror, Clock-stop-OK, Setting-reset GPIO: io=255, o=255, i=255, unsolicited=1, wake=1 Codec: Cirrus Logic CS4208 Address: 0 AFG Function Id: 0x1 (unsol 1) Vendor Id: 0x10134208 Subsystem Id: 0x106b7200 Revision Id: 0x100300 No Modem Function Group found Default PCM: N/A Default Amp-In caps: N/A Default Amp-Out caps: N/A State of AFG node 0x01: Power: setting=UNKNOWN, actual=UNKNOWN, Error, Clock-stop-OK, Setting-reset GPIO: io=255, o=255, i=255, unsolicited=1, wake=1 --endcollapse-- I will also attached complete alsa-info and dmesg.

Might the under laying acpi issue also effect the backlight? As specified in this bug: https://bugs.freedesktop.org/show_bug.cgi?id=67454 ?
(In reply to Miek Gieben from comment #4) > Might the under laying acpi issue also effect the backlight? As specified in > this bug: https://bugs.freedesktop.org/show_bug.cgi?id=67454 ? From the above mentioned link, it doesn't seem there is /sys/class/backlight/acpi_videoX interface available, so shouldn't be related to ACPI.
Hi Sam, If you do: # cd /sys/power # echo devices > pm_test # echo mem > state Does sound work well then?
For HDMI, is there video output after suspend and resume? If yes, I think this should be a HDMI module issue. BTW, did this work on the old kernel?
Note, as I added in https://bugzilla.kernel.org/show_bug.cgi?id=60811#c24, that I cannot reproduce this anymore.
