What is the correct or proper Windows 7 or 8 audio setting to ensure that I can play the High Res. music from HD Tracks with 24 bit depth and 96 or up to 192 KHz sampling ?
Any kind of suggestion would be greatly appreciated.
That's going to depend on the DAC/sound card, software you're using,etc. In Win7 go to Control Panel -> Sound and check the Properties of the device you're using and set appropriately. In my software there is a "Supported Formats" and "Advanced" tab that you can play with (and test). There may also be settings in your playback software (e.g. JRiver, Foobar) that may need to be adjusted but generally they just play what you feed them. Finally, there may be software that may come with your particular hardware (like my ASUS STX soundcard} and it would also need to be looked at to ensure it is set up as you wish.
1. Check Control Panel --> Sound (select your device, configure or check Properties) look for a "Supported Formats" tab (encoded formats and sample rate selections) and "Advanced" tab (bit depth, sample rate).
2. Check your playback software settings
3. Check any included software that may have come with your hardware.
P.S. It looks like Win8 is similar on the Sound settings look, feel options.
HDtracks now downloads ALAC. And since the iTunes media player accepts ALAC and now supports WAS you might just want to use iTunes as your media player. It addition to being a very intuitive media player, its library, internet radio, metadata, music and movie store, and organization features make it very convenient too.
