Vista DRM Bites CD Audiophiles

It would appear that Vista’s DRM protection is for more than just “premium content” – even DRM protected “CD’s” apparently won’t play through S/PDIF (optical) outputs whereas they work just fine under Linux.

My test system’s high-end audio outputs are S/PDIF (Sony/Philips Digital Interface Format) compliant. S/PDIF is probably the most common high-end audio port around for PCs today. It also has no built-in DRM (digital rights management) capability, and that turned out to be an important matter. […] When I switched back to Vista, I tried to play Wilco’s Yankee Hotel Foxtrot CD. Whoops! Not a single sound emerged from my speakers. After a little investigation, I found that Vista disables media outputs that don’t incorporate DRM, when you try to play DRM protected media through them.

Quite sad really given that Vista couldn’t handle his on board RealTek ALC 882 audio chipset either!

That was a kick in the head. I have a fully legal CD in my hand. Any other version of Windows will play it, Linux will play it, Mac OS will play it, and my CD player will play it, but if you’re using S/PDIF for your computer-driven audio and Vista, you’re out of luck. If you have a card with a Toslink optical digital audio port, you will be able to play it.

Vista’s DRM really is Defective by Design.
