I have a windows pc running itnues to my av receiver over HDMI

Does anyone know how to get itunes to send unprocessed sound to the receiver?
 
Well given that there is a volume control on iTunes, there must be some processing.

If I watch a movie I can send the dts audio to the receiver and it will let the receiver decode it rather than the pc. I presume I can do this with mp3s too
 
If you're talking about music, bit-perfect, and Windows upsampling everything to 48hz, then it involves a lot of faffing and I dunno if you can even do it on iTunes in the way that you can with say, Foobar2000 or J-River Media and the WASAPI "exclusive mode" plug-in.

You need specific soundcards, that are either good to go out the box or can be flashed with specific drivers at the very least to even get started.

This is why I got a Mac for iTunes since OSX is bit-perfect out the box as long as you leave iTunes volume alone and turn off any of the EQ effects, and can be output either through USB or SPDIF.

If this wasn't about bit-perfect ignore the above lol.
 
It sounds to me that what he's asking is if itunes is capable of providing bitstream output in the same way that a dvd/bd player outputs DD/DTS to then be decoded via an external receiver, presumably for 5.1 surround sound. TBH I have no idea if it supports it or not.
 
Volume control at 100% will be unprocessed if you're bypassing windows kmixer.

Yes iTunes will output DTS to a receiver (on a mac at least)

Yeah this is what I am talking about

i did some reasearch- WASAPI is available for Itunes, but only on 32bit windows grrr. I have a 64bit install
 
Airport Expresses won't resample the audio in files that are sent to them over the network, but I don't know how you'd be able to incorporate that into your set up. Windows is a bit of a pain when it comes to this stuff!
 
I know, I had all these grand plans to make a little HTPC, sort out WASAPI, use J-River with their iPhone app... but in the end it was just way less hassle and faff-time to join the white shiny side, at least for the audio side of things. One of those cases where it really does 'just work' ha ha.
