Hi @audiohobbit ,Hi Darin,
would an USB audio interface like this one do the job: https://tascam.com/us/product/us-16x08/faq
It has 8 analog line ins and can convert each of them to one ASIO channel (whatever that means...). So I decode DTS etc. with my AV-Receiver into 7.1 analog channels and feed them to this audio interface into the PC, then OOYH does its magic and outputs the 2ch processed headphone signal (also via the USB audio interface)?
Do you mean this would work?
If so, how do I tell OOYH which channel is L, C, R etc.?
Sorry about not responding sooner. Somehow I missed the notification of your post.
But in theory, that device would work. The trick would be that you would have to use "DAW" software (Digital Audio Workstation), to route the incoming audio signals to the Out Of Your Head Virtual Audio device. Since that interface is designed for use with DAW software, you would setup each of the input channels to output to the appropriate channels and setup the Out Of Your Head Virtual Audio device as the output device in the DAW. The DAW will see the Out Of Your Head Virtual audio device as an 8 channel audio card. Then you would just "monitor" the 8 input channels in real-time so the inputs would be fed to the outputs in real-time.
I am not sure what the latency would be though for watching movies or gaming.
