When I installed the AV-710 last weekend, I used the green jack on the back, outputting to my Logitech Z-340 2.1 speakers and the headphone jack on them to test the "foobar 5.1 headphone headphone experience". It was working fine per instructions here in bold.
9. Enable 2CH (not High Quality mode) by clicking the appropriate circle.
10. In Foobar, select WASAPI (envy24 speakers) as the output device.
Today, I read that the lower black port actually runs off the better Wolfson DAC, hmm. I went into the Envy control panel and switched the digital out to "S/PDIF out enable" and "PCM only", "2 channel Hi Sample Rate", and changed the sample rate to "96KHz". In foobar2000, there are 2 options for the "Envy 24 family audio controller WDM" (a) speakers (b) Digital audio (S/PDIF). I set it to the digital audio S/PDIF mode and now there is audio streaming out the lower black jack (haven't tried optical) port to my speakers and my 5.1 channel headphone mode still seems to work ok.
Are these the settings I should use?
Next up, I have a early 90s Rotel RC-960BX preamp and RB-960BX amp, B&W DM610 speakers, excellent little 2 channel setup. Can I do this below in bold?
AV-710 black port > 3.5mm to dual RCA jack cable > preamp > amp > B&Ws
I also have an old 5.1 channel Pioneer Elite VSX-24TX, could it be used instead? Thinking of a 2.1 setup or maybe even 5.1 if it works.
Another angle is just buying better powered PC speakers for WAF usage and use the old Logitech Z-340s elsewhere.
Sorry for all the questions, wasn't sure if I should post this on the 5.1 head phone experience, which I really like by the way, or here.
Update: Tonight I temporarily tested using the Rotel RC-960BX preamp / RB-960BX amp, B&W DM610 speakers setup as described above. Once I unplug the AV-710, I had to reboot to get foobar2000 to work again, then all was well. I am testing with 320 bitrate Tchaikovsky Nutcracker Suite music and noticed a couple times it sounded garbled a couple times for some reason, never noticed it using my Logitech Z-340s. I also noticed it sounds really smooth on the Logitechs, clear but a little harsh on the B&W setup for some reason. Not sure, maybe it is because I've gotten used to the Logitech setup, haven't used the other stuff in years.
