OK, this is how it went:
In the interest of experimenting with new ways of doing it, I first tried playing the WAV file via optical from my laptop running foobar2000 at 44.1KHz. On the receiver, it said spdif updating, but no dsp writing... failure
. Turned it off by pressing Standby on the unit.
I then put the cd in (burned with "Sonic DigitalMedia Plus v7" that came with my pc) the laptop drive and tried it also through foobar2000... failure again, see above.
Next, I dug out my old Sony DVP-NS725P dvd player, went in the setup menu, turned DTS off, set output to PCM, and proceeded with the update. This time, it wrote all the DSPs but it got stuck at spdif updating. I waited the mandatory 10 minutes, turned it off, then on again and voila!! DSP's were updated.
I have an 805 with 1.06 main FW. Only the first DSP was changed.
I put the Fly in and NO POPPING NOISE COMING FROM IT.
Again, I would like to thank the AVS man of the year joerod
!!! Whether or not Onkyo comes out with an official release, this has been working until proven otherwise. And make no mistake about it, these receivers are under more scrutiny now than ever before. I'm watching mine like a hawk!!!
I'm anxiously waiting for the 805 main FW update!!
