I have setup with:
HP envy notebook:
Intel i7-6500 CPU 2.5 GHz and 2.6 GHz,
Ram 8.0 GB,
64 bit OS x64 based processor
Windows 10 latest updates installed.
USB 3.0 from HP out to iFi nano iDSD DAC
RCA out from iFi to RCA audio 2 channel input to
Onkyo TX RZ830 AVR:
Contains same DAC (AKM AK4458) which is in one year newer model TX RZ840 (This model is listed as tested and found to work
With Roon). Model 830 has not been tested by Roon.
The above configuration works perfectly with purple stars at all audio path locations for audio tested up to 192/24 through Quobuz via Roon on HP with LOSSLESS message at top of path listings.
Problem:
When I try alternative path using HDMI out from HP to Onkyo HDMI 2.1 cable input using wasapi exclusive mode I get purple star for input at 192/24, purple star for RAAT with no downgrade for 192/24 BUT GREEN STAR at last stage for OS Mixer. At top instead of LOSSLESS it says now HIGH FIDELITY.
My question is how do I know what the final output from this HDMI connection am I getting as note from Roon states they give green star at the end as system is not tested as Roon ready so they cannot say lossless?
Thank you for your help as I believe the HDMI path should work with Roon as there are hardly any differences between Roon model 840 tested and my 830âidentical DAC, e.g.

Selected Features
Amplifier
Onkyo TX-RZ840 and Onkyo TX-RZ830 have 9 channel amplifiers. They both deliver 120 W (8 âŚ, 20 Hz - 20 kHz, 2 channel driven) and have stable performance at 4 ⌠load. Since 2016 all receiver manufacturers have dropped front wide channel support and these models are no exceptions.
Video Features
Both receivers support 4K passthrough up to 60p. The receivers support HDR10, Dolby Vision.
HDR10
High-dynamic-range (HDR) video has greater dynamic range than standard-dynamic-range (SDR) video with brigter whites and deeper blacks. HDR10 was announced on August 27, 2015, by the Consumer Technology Association and uses the wide-gamut Rec. 2020 color space. It sends static metadata via video stream to the TV which calibrates its screen brightness and color according to that. HDR10 supports up to 1000 nits of brightness and 10-bit color which corresponds to 1024 shades of the primary RGB colors.
Dolby Vision
Dolby Vision is an update to HDR10 by adding dynamic metadata that can be used to more accurately adjust brightness levels up to 10,000 nits maximum brightness on a scene-by-scene or frame-by-frame basis and supports up to 12-bit color depth (4096 shades of RGB) and 8K resolution.
Dolby Atmos and Dolby Surround upmixer
Onkyo TX-RZ840 and Onkyo TX-RZ830 support Dolby Atmos with its Dolby Surround upmixer. They can be configured upto 7.1.2 or 5.1.4 channels using internal amplifiers or upto 7.1.4 channels by adding 2 channel external amplifier.
Dolby Atmos is the first cinematic audio format in which sounds exist as individual entities, called audio objects. In Dolby Atmos, any sound - the helicopter, a car screeching around a corner, a melodic bird call - can exist as an independent audio object, free of channel restrictions. They can be precisely placed and moved anywhere in your room, including overhead, to flow above and around you in three-dimensional space. Through the use of audio objects, overhead sound, and all the richness, clarity, and power of Dolby sound, Dolby Atmos turns your room into an amazing place for entertainment. Youâll feel like youâre inside the action, in ways youâve never experienced before.
Dolby Atmos for the home represents every sound in the original cinema mix as an audio object. Extensions to the Dolby Audio⢠codecs, along with an advanced scalable algorithm, allow Dolby Atmos to be delivered via Blu-ray Disc and streaming media. A spatially-coded substream is added to Dolby TrueHD or Dolby Digital Plus. A Dolby Atmos audio/video receiver (AVR) adapts the cinema experience to your home theater from seven speakers to as many as 34 in 24.1.10 configuration, recreating the original artistic concept. The format supports up to 128 simultaneous independent audio objects in a mix for rich, realistic, and breathtaking sound. It recreates the directorâs original concept through descriptive metadata to provide customized playback for home theater and delivers sounds above you through overhead speakers, special upward-firing Dolby Atmos speakers, or a Dolby Atmos enabled sound bar.
If the content is not mixed in Dolby Atmos then the Dolby surround upmixer will expand the audio to all channels including ceiling speakers. The upmixer has replaced the Dolby Pro Logic II family with improved upmixing algorithms.
DTS:X and Neural:X upmixer
Onkyo TX-RZ840 and Onkyo TX-RZ830 support DTS:X with its Neural:X upmixer. Both of them can be configured upto 7.1.2 or 5.1.4 channels using internal amplifiers or upto 7.1.4 channels by adding 2 channel external amplifier.
A technique used in DTS:X is similar to the one used in Dolby Atmos. Instead of a fixed number of channels, DTS:X defines object locations from the listener in polar coordinates. An a/v receiver then dynamically renders sound according to the current speaker configuration. The speaker layout employed by DTS:X is the sum of Dolby Atmos and Auro-3D. It has standard 7.1 channel base layer, a 5 channel height layer above the base layer on the front and side walls, and 3 rows of speakers on the ceiling.
DTS Neural:X is an upmixer that can take non DTS:X content and upmix it to the DTS:X speaker layout. It has replaced the DTS Neo family with improved flexibility.
Dynamic Audio Amplification
Onkyo TX-RZ840 and Onkyo TX-RZ830 feature Dynamic Audio Amplification which is Onkyoâs amplification philosophy that focuses on capturing the energy and dynamism contained in the audio signal and reproducing it without loss. Audio signals are not static like a test tone, but rather a countless collection of constantly moving waves. While static measurements such as S/N ratio and Total Harmonic Distortion are important, Onkyo believes that excellent dynamic and transient response is the key to emotionally involving sound. Dynamism - the âlifeâ in music - is achieved when the amp can respond to changes in the signal instantaneously, so notes start and stop naturally and the nuances in attack, decay, sustain, and release are voiced with conviction. Onkyo home theater receivers represent the culmination of almost 70 yearsâ experience in amplifier design. The unique elements of their amplification system comprise high-current, low-impedance architecture to accurately control large speaker cones while enabling instantaneous response to dynamic changes, and discrete wide-range amplifier circuit topology to eliminate phase shift for clear and accurate audio imaging.
THX⢠Certification
Onkyo TX-RZ840 and Onkyo TX-RZ830 are THX⢠certified which offers optimal performance, superior quality and seamless integration. THX works with partners from the ground up, so that certified products deliver professional quality audio-visual experiences right out of the box. They only certify the very best products with uncompromised quality, performance and consistency. They ensure that THX certified devices play well with lower performing devices and components. THX listening modes make the receiver to have one speaker set up for movies, music and games. They are tested for power output, bass management, signal-to-noise ratio and feature RE-EQ, timbre matching, boundary gain compensation and THX Loudness Plus.
Advanced Music Optimizer
Compressed music enhancement in Onkyo TX-RZ840 and Onkyo TX-RZ830 is done by Onkyoâs Advanced Music Optimizer. While MP3 or AAC files may sound fine through the headphones of your portable digital player, the limitations of these files can be exposed when played back through a quality home entertainment system. This is because a significant amount of high-frequency bit information is lost during the file-compression process. To counter this, Onkyo has designed the Advanced Music Optimizer to compensate for lost bit information and improve the quality of compressed audio signals. This results in a clearer and more expansive sound. Also included in this technology is a loudness correction feature that further improves the audio character of compressed files.
Connectivity
Onkyo TX-RZ840
Onkyo TX-RZ840 can be connected to internet using ethernet cable or built-in wi-fi adapter. It can also connect to bluetooth devices via built-in bluetooth adapter. The Receiver works with SONOS and supports AirPlay 2 after firmware update. It has 7 HDMI inputs with HDCP 2.3 copy protection.
