having trouble playing lossless audio to my roon ready device. I am using my lenovo yoga 920 13ikb laptop as the server and my roon ready device is my samsung Q990f speakers.

Try a higher sample rate audio source. And/Or set the sample rate to 44.1khz limit in device settings for Roon to prevent upsampling. You may have an upsampling setting in muse settings as well, if that doesn’t resolve the signal path issue.
It should then say “Enhanced”. I also have the q990f and I don’t know how to disable the Samsung ai processing which makes it not show “lossless” signal. I can set it to “Standard” audio mode and disable spacefit pro, but it still shows this.
I’m no expert, but I hope this helps you in some way to troubleshoot.
Hi Nicholas_Martin,
Thank for your advice.
I have spent a day alone trying all different ways to solving this so I really appreciate your help.
I would ideally love to play all audio to the highest achievable quality with my current setup, fingers cross, so capping the sample rate is something that doesn’t sound ideal.
I saw a chat with a guy who set up a usb c to hdmi cable to achieve lossless which I am considering doing however I sense there may be a way to resolve this quicker.
It would seem that the soundbar only accepts 48 kHz or 96 kHz sources (which are normally associated with video playback.) Roon resamples as it as computer (Roon Server) more precision than a solid-state device.
In the first example, 44.1 kHz was upsampled to 48 kHz by Roon (and subsequently upsampled to 96 kHz), and in the other, 176.4 kHz was downsampled to 96 kHz. This is typical of this kind of device, which applies its DSP to emulate multichannel with only a few speakers.
The clue is in the signal path. Roon has no control beyond the Roon logo.
Hey @Louis_Makoni,
Thanks for writing in! @mjw is quite correct in the above response - let me know if you have any additional questions here. 
Yes, I can confirm that the Q990F via WiFi input using the “Roon ready” audio connection is limited to 96kHz, while the soundbar itself can handle up to 192kHz audio signals via hdmi (and possibly optical connection? Haven’t tried that yet).
Your mileage may vary with using usbc to hdmi conversion; I did end up showing a lossless signal with ASIO4ALL using a usb-c to cdmi converter, but the sound was very thin and lacking quality. I tested output from usbc via both PC and iPhone, but didn’t have a different cable to try.
I believe if you use an exactly 96kHz audio sample that it will still not show “lossless” but instead “enhanced” because of the built in processing done real-time by the Q990F soundbar. It should be blue (enhanced) instead of green (high-quality) that way, but not purple (lossless) for the signal path indicators. You can click the colored indicators to read more info.
