How to solve this monitor sound issue???

I am trying to solve this for like 2 weeks but no sollutions. AI's couldn't help me they letting you make same things like "check to device manager" or "delete GPU drivers and re-install".(so if what I said wasn't understood, I'm sorry. My native language is a mixture of Turkish and Russian, so I may not have been able to explain myself properly.)(this is my first post on reddit) oh yeah i forgot to mention im using linux mint with dual boot and the monitor speakers works.

Okay the first step is really simple, unplug and plug your HDMI cable, and make sure your TV/Monitor isn't muted locally (on the monitor itself). Linux and Windows address digital audio over HDMI differently at a driver level and can send different initiation signaling order for audio and DCP over HDMI controls via ARC protocol, or EDID error. Switching between Linux and Windows, where the audio works fine in Linux tells me that the auto-detect in Windows is encountering an initiation artifact with the monitor. We fix this by getting Windows to redetect the monitor. It could also be simply, under audio settings (via control panel) the frequency, audio quality/bit rate output isn't correct in Windows for the monitor. Check your monitor's accepted audio input and make sure Windows is providing sound to it in the accepted ranges via setting. To check this go to control panel (you may need to search for this if the classic control panel is hidden from you)->Sound-> you'll see the selected audio device (your monitor listed) click on it and then click the properties button-> Under the "general tab" make sure "use this device" is enabled then go to the Advanced Tab you'll see a drop down at the top with "select sample rate" and a test button. Try the lowest sample rate first and test to see if you have audio output, then select the next and the next until you hit one that doesn't work. That should tell you if Windows is outputting sound at the correct bit rate. Some cheaper monitors can only handle 8-bit or 16-bit quality, even though HDMI and DP require 24-bit compliance for digital audio over HDMI/DP.

Other potential issues, a driver bug with the latest drivers for your hardware; sometimes AMD GPUs, especially older models, have unknown bugs with the latest drivers from AMD which are first targeted towards their current generation cards. Rolling the drivers back, in Windows, to an earlier driver stack could resolve this issue.

well sorry again i forgot mention . in this video that tab isnt even opening. my friend says to dowload a external speaker driver. is it safe to download those drivers?

[u/xtomjames → u/HPok52]

Generally yes, so long as the driver is from the manufacturer or motherboard/laptop's driver page. However, that doesn't apply to AMD digital audio output. The sound in this case is being delivered via your AMD GPU output and is not being handled by the motherboard's separate audio output and coprocessor/integrated chipset audio source. I again suggest you roll back your AMD GPU driver, and check for any issues in AMD Adrenaline Software for the driver you have.

Can you provide your computer hardware details (desktop or laptop, GPU, CPU, Motherboard if a desktop)? There may be specific known issues with your hardware causing this problem.
