Finally after half year I fixed it. The filesystem had error. I did:

• downloaded ubuntu iso on host machine
• attached iso as CD-ROM
• turned off UEFI
• turned off boot from hard drive
• set up CD-ROM as first device to boot
• started virtual machine and selected boot from CD-ROM
• after ubuntu started I launched gparted, selected disk with HA and run check/fix on data partition (twice)
• powered off virtual device
• unchecked boot from CD-ROM, checked boot from HD and moved it to first position
• moved HD in boot order to top
• started the virtual machine. no Ctrl-D was required

1. Download MX player(for video) and playmusic/Spotify or any app for music/MP3 playback.
2. Open MX player
3. Then go to local Player settings> Player> Playback section> and uncheck play alone option.
4. Go to equaiizer settings (of max player) and make everything( all frequencies) to 0.
5. Now you can play any video on MX player with zero volume while simultaneously playing music using another MP3 player app at full volume.

Note! If you have a samsung device you can do it by samsung’s built in soundassistant settings.

If you have a headless machine (ie: no monitor plugged into it) you’ll need to either install a “HDMI headless dummy connector” or you can install a Video Dummy Package:

sudo apt-get install xserver-xorg-video-dummy

Then add a configuration file for it:

sudo vi /usr/share/X11/xorg.conf.d/xorg.conf

and paste this (adjusting your desired resolution)

Section "Device"
    Identifier  "Configured Video Device"
    Driver      "dummy"
EndSection

Section "Monitor"
    Identifier  "Configured Monitor"
    HorizSync 31.5-48.5
    VertRefresh 50-70
EndSection

Section "Screen"
    Identifier  "Default Screen"
    Monitor     "Configured Monitor"
    Device      "Configured Video Device"
    DefaultDepth 24
    SubSection "Display"
    Depth 24
    Modes "1920x1080"
    EndSubSection
EndSection

Then reboot the machine and voilá

Both LEDs and fluorescent lights require a buffer between the lamp and the power supply. While fluorescents use ballasts, LEDs use drivers. Even though the function of ballasts and drivers are quite similar, most documentation prefers ‘drivers’ to be associated with LED lamps and ‘ballasts’ to other traditional light sources. Ballasts and drivers are essential components to trigger and control the light fixtures.

Credits and Thanks goes to BlackMesa123 for this post for OEM patch script.

Important Note for Pie – There will be OEM unlock option there in developer setting but it will be disabled and can not enabled, this is because of it is hacked. Just ignore it. You can not boot device with TWRP if it is really disabled. Also If magisk app may not appear then simply download Magisk_for_Pie.apk from below attachement and install as regular app.
