Yea my issue pertains mainly (almost exclusively) to games and web browsing (you tube). When I use a dedicated player such as Jriver I have found where to set the output. The "dolby digital" claims that games make it would seem refers to cgi scenes and not in game audio which is rendered in pcm on the fly so expanding those from 5.1 to 9.2 just doesn't seem possible. Now that I have an external DAC pretty much all my 2ch audio will go through it and then out to a 2ch pre-pro and then amp. What confused me was that I just recently upgraded from a gtx 580 soundcard which was limited to pcm transmission only to a gtx970 which claims to support bitstreaming and decoding the high-def codecs (Dolby True HD and DTS-HDMA) from the Nvidia website description Apparently my old 580 couldn't send bitstream even if software player told it to (like the first gen ps3) but rather had to have it transcoded to pcm and could then do multichannel pcm while the 970 will allow bitstreaming if software (player) tells it too. I think at this point I have a handle on it - thank you all. (also it seems many of the games that claim DD 5.1 or DTS are claims for console versions - how that is managed IDK- nor does that matter as I chose to upgrade my PC [CPU,GPU, RAM.Mobo] instead of get a next gen console)

Actually I found this which seems to answer my question regarding games Apparently you can use DDL to encode pcm back to DD on the fly which is pointless to re-encode something once it has been decoded. It looks as if I will not be able to expand my soundfield on video games to encompass additional channels. For movies etc. I use a dedicated disc player so no troubles there - thanks everyone.

Okay so I just received my first external dac (outside of Fiio combo used for mobile devices), a Music Hall 25.3 SS + Tube Dac / Amp combo. My question is regarding config settings. In my windows audio device properties do I want to choose "24bit USB audio device" or "Jriver Media Center". I can choose either and music will play but I don't know if choosing one is preferable over the other (for example if I choose USB audio device does this nullify any settings i.e. WASAPI / ASIO etc. in Jriver). I am new to both Dacs and Jriver so any guidance would be welcomed. Also the Music Hall has a headphone amp and while it is okay with several of my phones the volume isn't very loud. It certainly is loud enough for listening but nowhere near what my other amps have produced. I would say it gets half as loud as my current amp Project Sunrise II from Garage1217. I was wondering if I changed the op-amps would this affect the volume or ability to drive different cans. I was thinking of replacing the stock opamps with some Burson opamps (or another comparable better opamp depending on cost). As always - thanks in advance for any assistance.

I have several video games that are listed as having Dolby Digital and DTS sound yet I still get PCM listed. What I am wanting to do is bitstream 5.1 sound so that I can expand to include additional channels via sound fields such as DTS Neo and expand stereo to 5.1 /7.1 but I always get pcm delivered to my avr and you can't expand that- unused channels appear used (they just get sent a 'blank' signal). BTW - thank you for the info about the player. At least for music I can set my Jriver Media Center to bitstream and can address things that way with it.

nobody has managed to answer my question yet - can somebody please tell me HOW to switch from multichannel pcm to bitstreaming via gpu HDMI. Nvidia states it is supported and so does windows "properties" but I can't figure out how to change the setting and have searched again and again and posted in forums but everybody spirals it into something other than the simple question

Hello all, can anybody tell me how to configure a windows pc (windows 7) to get bitstreaming from an Nvidia gpu (gtx 970) via HDMI. Currently I am receiving multichannel PCM via HDMI but would prefer to bitstream from my pc to my AVR and/or pre-pro.
