This morning I made new tests and I add some pictures.
First, my audio driver is High Definition Audio Device
and I have no crackling/static noise (I followed the procedure from Denis Fyodorov at post #2423
I have connected my laptop (hdmi port) to the soundbar (hdmi1) with the cable supplied with the soundbar.
Windows found the SB and informations are (see picture 1) :
- Name: EP-HDMI-RX
- Audio driver : High Definition Audio Device
- Connector : HDMI
- Audio processing : DTS Audio / Dolby Digital Plus / DTS-HD / Dolby TrueHD / Dolby Digital / Dolby Atmos (DD+, MAT 2.0 & 2.1).
- Enhancements : not activated.
- Bit stream : is on Dolby Atmos but I have a long list of choices.
- Spatial sound : Dolby Atmos for home theater.
I made a test with the movie Saving Private Ryan
(.mkv) an MPC-HC, audio track is TrueHD Atmos [email protected] Kbps[eng] (truehd, 48000Hz, 7.1, s24)
On the screen of the SB there is no mention of Dolby Atmos
(refer to User Manual, section 05 "Connecting using ann HDMI cable (Dolby Atmos supported)"
, note point 4 : "When Dolby Atmos is activated, "DOLBY ATMOS" appears in the front display." page 16).
I have no sound from the 4 ambiophonic speakers, it's just a 7.1 but not a 7.1.4.
Do I miss something in my setup or in MPC-HC ?
Thank you for your help.
To have your PC/laptop send a Dolby Atmos signal, you must also ensure that you have your media player configured properly. This is different for every player. In general, you are looking for settings that send unprocessed bitstream audio. For example, in MPC-HC (media Player Classic Home Theater):
1) In MPC-HC, go to Options
> Internal Filters
> Audio decoder
2) In the Properties
window, on the Audio Settings
tab, under Bitstreaming (S/PDIF, HDMI)
, select all check boxes (they mean that for these formats, the signal will be processed by the soundbar rather than your PC), especially the Dolby TrueHD
(required for Dolby Atmos) and DTS-HD
(required for DTS:X) check boxes. See the attached screenshots.
How to check that you are bitstreaming unprocessed audio: when you change volume in your media player during playback of Dolby Atmos or DTS:X audio, it will not have any effect; only changing volume on the SB will work. Also, when Atmos/DTS:X is properly detected by the SB, not only text will flow for a few seconds on the SB display, but also the Sound Mode button (which has options STANDARD, SURROUND, or SMART.) will not have any effect.
Also, obviously, your video file must have an Atmos track.
As far as I know, the Spatial sound: Dolby Atmos for home theater
option in Windows is not required for movies with Dolby Atmos (only for games that support the Dolby Atmos sound). To watch a movie, you don't even need the Dolby Access app installed. Just make sure you configure your media player to send bitstream audio via HDMI and that the video has the Atmos audio track selected.
As for your TV not supporting ARC, this is not a problem at all as long as you connect the sound source (laptop in your case) directly to the soundbar. In this scenario, TV is not sending any signal; it is only used to output image. And this is the recommended way to set up your system because ARC has limitations, and cannot send high bitrate object based audio such as lossless Dolby Atmos or DTS:X. It can send DD+, which may have Atmos encoded into it, but it is lossy. So, to have the best possible sound and not worry about limitations, connect your PC directly to the SB rather than to TV with ARC.
