[SOLVED] E7450 HS: No sound after lid close

I recently noticed that sometimes I have no sound. Everything starts to work as soon as I reboot.

First thing that I suspected is that I have no sound after sleep. It turns out that if I choose Sleep from main menu, I have sound after wake, with or without power supply connected. Finally I figured out that if I close the lid while I am not on power supply, laptop goes to sleep (as expected), but I have no sound after wake.

Everything looks correct in output screen even after sound stops working.

I checked my config. Layout ID is 11 with Lilu and AppleALC and I have EAPDFix. Hibernation is properly disabled:

System-wide power settings:
Currently in use:
 standbydelay         10800
 standby              1
 womp                 1
 hibernatefile        /dev/null
 powernap             1
 gpuswitch            2
 halfdim              1
 networkoversleep     0
 disksleep            10
 sleep                1
 autopoweroffdelay    28800
 hibernatemode        0
 autopoweroff         1
 ttyskeepawake        1
 displaysleep         10
 lidwake              1

I am using patched files that Jake made from my origin while I was struggling with my first HS installation.

Am I missing something obvious as usual? Should I try with patched files from latest E7450_Disable840M_A17_HS.zip instead?

At the end I removed EAPDFix.kext and replaced it with CodecCommander.kext

 

I had to modify Info.plist inside CodecCommander.kext, since there is no entry for my card ALC3235 (ALC293).

<key>10ec_0293</key>
<string>Realtek ALC3235</string>

My codec dump is very similar to ALC292 dump (0x1a and 0x15 are basically same), so I just duplicated and adjusted ALC292 config.

My speaker and headphones now works even after lid close.
