    SPDIF output activation on the motherboard (with ALC887) without SPDIF


    I was able to activate the S/PDIF output in Fedora 27 (from pin 48 ALC887. I also added a 20k resistor from pin 33 to ground) on the board without S/PDIF - Gigabyte GA-C1007UN.
    I used hdajackretask (hda-jack-retask, alsa-tools-gui).

    file /sys/class/sound/hwC0D2/init_pin_configs
    0x11 0x411111f0
    0x12 0x411111f0
    0x14 0x01014410
    0x15 0x411111f0
    0x16 0x411111f0
    0x17 0x411111f0
    0x18 0x01a19c40
    0x19 0x02a19c50
    0x1a 0x0181344f
    0x1b 0x02214c20
    0x1c 0x411111f0
    0x1d 0x4004c601
    0x1e 0x411111f0 <-----
    0x1f 0x411111f0

    file /sys/class/sound/hwC0D2/user_pin_configs
    0x11 0x411111f0
    0x12 0x411111f0
    0x14 0x01014410
    0x15 0x411111f0
    0x16 0x411111f0
    0x17 0x411111f0
    0x18 0x01a19c40
    0x19 0x02a19c50
    0x1a 0x0181344f
    0x1b 0x02214120
    0x1c 0x993301f0
    0x1d 0x4004c601
    0x1e 0x014b1180 <----- change (0x1e = probably S/PDIF)
    0x1f 0x411111f0

    (hwC0D2 = ALC887)


    I don't know how to do the same in Windows 7 64-bit. I tried to use High Definition Audio Utility 64-bit program - with no effect.
    Menu File -> Local machine codecs -> ... - result:
    "No HD Audio debug interface found. Please make sure the class driver is installed."

    hdausetup_x64.msi (HDAU.exe) - High Definition Audio (HD Audio) tool - Windows 10 hardware dev | Microsoft Docs
    pin config: Pin configuration guidelines for High Definition Audio devices - Windows 10 hardware dev | Microsoft Docs
    (The original links were broken by the forum software - by the presence of parentheses in them)

    I tried through regedit - in the key
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E96C-E325-11CE-BFC1-08002BE10318}\0007\Settings\Drv5859_DevType_0887_SS1458a002
    I added binary value "Pin1E": 014b1180 - with no effect.

    Thanks in advance.
