Have a sigmatel hd chip together with intel 945 chipset on my laptop, and windows just have better sound quality than mint. Not that its some real faults with it, but it seems like hd audio isnt ebabled or its running the '97 codec.
Some way to get it to the windows audio quality level? Now it sounds like low-fi or like a old cassette recorder from the 80's. Well you get the figure, difficult to enjoy the music..
