From here finally i can get new version of hdx_hpext_hsa.inf & hdx_hpext_sr_rtkgen3p1.inf to version 6.0.9703.1 from original version 6.0.9611.1.
However, what I want is a newer version, the same version as the realtek audio driver 6.0.9749.1.
Can anyone here give me a link to download those 2 things?

@Banlix, Welcome to the HP Support Community!
Thanks for reaching out about your query regarding your HP 14 inch Laptop PC!
We're thrilled to have the opportunity to assist you and provide a solution.
I understand you’re looking for an updated version of the hdx_hpext_hsa.inf & hdx_hpext_sr_rtkgen3p1.inf files to match the Realtek audio driver version 6.0.9749.1 for your HP 14-d3000 Laptop PC.
Currently, the latest available version for your device is 6.0.9703.1, which is why you’re seeing this in the driver section on the HP support page. If 6.0.9749.1 isn’t listed under your device’s official drivers, it means that this version has not yet been validated and released for your specific model.
HP releases driver updates only after thorough testing to ensure compatibility and stability with your system. While newer versions may be available for other models, they may not be optimized for your hardware. I recommend keeping an eye on the HP Support page for your device, as any future updates will be listed there once they are officially available.
If you have any further questions, feel free to ask. Happy to help!
Take care, and have an amazing day!
