I already installed Windows 7 and Windows 10 several times. Download the Windows 7 drivers from the official website. Even with an audio tester that comes in the gparted and nothing. It is only heard by headphones or by bluetooth. I think the problem is in the integrated speakers, which I also tested separately. I tried and there is continuity between the speaker connector on the board and the integrated legs. That's why I think the pill is goat. Thanks for your help but I don't have to replace it.
Friend the realtek chip is very similar
If you have a 272 or 262, it works only if it is not a very advanced one that is in the range of 700 and 600
Now if you want to discard if it is the linux test chip I recommend mint on 8 and you will leave doubts but without a doubt it is the chip or a component next to the diagram below the pc to see that you can find greetings and luck
