Hello. You can try [url]http://stackoverflow.com/questions/211484/how-do-i-capture-the-audio-that-is-being-played[/url]. Or you can use windows API (like [url]https://msdn.microsoft.com/en-us/library/windows/desktop/dd316551%28v=vs.85%29.aspx[/url] (untested)). Or you can write own qemu audio driver to get audio from Xen/Dom0 in virtualized environments ([url]https://xenbits.xen.org/gitweb/?p=qemu-xen.git;a=blob;f=audio/audio.c#l47[/url] (It works for me fine)).

[quote="erlog"]How about on Linux?[/quote] It depends (OSS, ALSA [url]http://tuxradar.com/content/how-it-works-linux-audio-explained[/url]). You can search for "loop" output configuration (ALSA - "snd_aloop" module). Or you can write own qemu audio driver to get audio from Xen/Dom0 in virtualized environments ([url]https://xenbits.xen.org/gitweb/?p=qemu-xen.git;a=blob;f=audio/audio.c#l47[/url] (It works for me fine and it is generic solution. SteamOS 2.0 (eg. Debian, vgpu k160q @ nvidia 367.27) works ok in client but some problems in games.).

Hello. And about NvIFR? How can I capture the game audio? Thanks.
