Does this only apply to video content (as the name would suggest), or does it apply to audio as well?

For example, the passage:

Some output types such as S/PDIF (Sony/Philips Digital Interchange Format) typically don’t have a suitable protection scheme available, so these need to be reliably turned off if the content so specifies.

implies that audio is affected, as S/PDIF is an audio interface.

The article also says:

...used to encrypt video and audio data as it passes over the PCI-Express bus, to prevent it from being intercepted and copied on the way to the graphics card.

Audio going to the graphics card? That does not make a lot of sense. 217.34.39.123 11:52, 2 February 2007 (UTC)[reply]

PUMA: Protected User Mode Audio (PUMA) is the new User Mode Audio (UMA) audio stack. Its aim is to provide an environment for audio playback that restricts the copying of copyrighted audio, and restricts the enabled audio outputs to those allowed by the publisher of the protected content[3] http://en.wikipedia.org/wiki/Security_and_safety_features_new_to_Windows_Vista#Digital_Rights_Management Dbiagioli 11:57, 2 February 2007 (UTC)[reply]

I fixed it with a new page, as both are part of the Protected Media Path. Patrick1982 21:56, 7 February 2007 (UTC)[reply]

hey, look at his blog entry: http://www.alex-ionescu.com/?p=31 the method does not work 216.15.122.216 (talk) 23:13, 18 March 2007

Alex never claimed to have beaten the PMP. In fact, his blog states explicitly that not only has he not beaten the PMP, but that his method was geared towards defeating driver signing and that he'd have no knowledge of breaking into the PMP. —Preceding unsigned comment added by 128.113.197.227 (talk) 08:36, 28 October 2007 (UTC)[reply]

Would it be possible to add some history? I added a local link to PUMA in my own knowledge base, perhaps 15 years ago or 10 years ago or something like that. As things changed, it would be nice if this wikipedia article could add history, e. g. when PUMA was first introduced, which vista version and such. This would help us hobby folks remember when things are a bit fuzzy, or when we forgot already, and also did not add entries into a local file. :D 2A02:8388:1602:6D80:3AD5:47FF:FE18:CC7F (talk) 18:10, 30 April 2021 (UTC)[reply]
