Why isnt my speaker output working on my HDMI TV turned monitor,while the display is fine(1920X1080,60Hz)? The speaker is fine as i have checked by different way including connecting to a laptop and setup box through HDMI.Also sometimes the display opens at same resolution but not that clear and not 100% scaled and at this time the sound output also works fine,but i have to change this and for this i just restart either my pc or just monitor and then the screen becomes fine but the sound output is gone. Every component is checked and working fine.Im using R5 3400g APU.Also every driver is updated. Screenshot(DRIVE link)- I mean every time I start the computer graphic is dumb and scaling is not good but the sound from the TV/monitor Connected through HDMI comes fine. To get graphics performance I have to restart my pc every time but in this case I have to compromise with the sound there is no sound output after restarting. First photo is after cold boot and second one is after warm boot. Also you can check the monitor info from here(connected through HDMI). Also other PC components are:Gigabyte B450M DS3H(latest bios), 240gb SSD , 80gb HDD, 8gb CORSAIR VENGEANCE 3000mhz RAm,VS450 PSU. The HDMI port and cable are also fine as i have tried the same with LAPTOP. Also i have mentioned that it works fine . The only problem is cold booting welcomes SOUND and warm booting welcomes GRAPHICS. I have literally tried every thing so dont push rubbish like try reinstalling drivers or check hardware and connections. Facing this issue from a long time and thus i hope for a quick and god response from your side.
So basically why it's changing from HDMI TO DVI-D
 I noticed something, cold booting opened screen in low

I have performed following (all in vain)=
1.Installing/Re installing Graphic Driver multiple times.
2. Clean boot.
3. DDU utility driver clean up.
4.Fresh windows installation.
5.disable the windows auto update in the "Show and
> hide" tool.
6.latest BIOS and the chipset version
> available for your Motherboard.
also i have scratched whole internet in vain.
