A:Answer Yes, this system does play audio from 4K ultra HD Blu ray/Blu Ray and DVD Discs (when connected to a Blu Ray player). This system also supports Dolby Atmos but in a 5.1.2 layout, not a 7.1 layout. Since current HDMI 2.2 usually defaults to 340 Mhz speeds instead of the optional higher speed, most users find that they connect their 4K Ultra Blu Ray player directly to their TV and connect an HDMI cable to the receiver for audio. This type of setup better supports the higher bandwidth requirements of HDR. Many 4K Blu Ray players have 2 HDMI cables out for exactly this reason. This specific receiver/speaker setup has been reviewed by many as a very good beginner setup for a small to medium size room, but the quality over time has been called into question by some users, thus an extended warranty for this unit is recommended.
