Advantage of this solution would be that you would need not change any settings on your HTPC and the AVR other than volume.
You might still experiment with the optical connection and the "rec out" settings as mentioned earlier. But that would require more changes to the devices' settings.
According to the manual it ought to be possible to route at least some sources (but not HDMI) to the optical output port. You ought to check that only a stereo downmix is sent to the "rec out" port as the headphone's input will probably not accept and decode 5.1 sound. Have you checked the RS175's optical input specs yet?
Good luck, and please report back…
I have an update here. Everything's working now. Every single source in my rack setup has been setup to stream audio through the headphone.
I tried the 3.5mm jack to rca y cable, attached the 3.5mm jack to the HTPC and the rca to the avr, switched the default sound to the headphone in the HTPC, and vola sound streamed through the headphone. Now here is the best part. I dont need to unplug the 3.5mm jack from the hptc each time i need to audio from the 7.1 speakers. All i have to do is switch the sound to HDMI from the playback device in the HTPC, and when i need to hear from the headphone just change the default playback to headphones in the sound settings in the HTPC.
Now here is another trick to make this work even better.
can change your playback devices with hotkeys.
I've setup hotkeys for hdmi CTL+SHIFT+H for HDMI and CTL+SHIFT+S for sennheiser Headphone, no need to open the controls for sound each time to switch it on and off.
I have EventGhost on my HTPC that also has a module to accept keyboard inputs on the HTPC, Now all i have to do is program my IRULE and add buttons/icons for headphone which will switch the avr to zone 2, and select the proper inputs and emulate the keyboard stroke that i mentioned above to switch automatically to the sound playback. Everything's permanent now behind the rack and irule takes care of switching inputs, sources and sound playback options through just one tap on the headphone icon.
Love the iRule remote.
By the way, another update.. for the XBOX i am using the Orei DA34 Digital to Analog Audio Decoder SPDIF/Coaxial 5.1-Channel Input to RCA L/R/3.5mm Headphone Output
As the Xbox has only optical output, and only the coverter that is capable of decoding 5.1 dolby/dts will work, other converters will cause static.
