HTPC and sound
Sound is an essential component of a home cinema setup. Its new surround formats, such as Atmos or Auro-3D, add dramatically to the overall experience.
The main feature of Atmos is the addition of height channels. Auro 3D consists of three distinct layers (base layer at ear level’, height layer and a top layer, which is a single speaker positioned directly above the listening position).
Going simple and cheap
The cheapest and simplest way to add the new surround sound formats in a home cinema setup is the incorporation of a soundbar with or without satellite speakers and subwoofer.
In general, the major Hollywood studios have adopted Dolby Atmos rather than Auro 3D. Thus, most soundbars adopt this format.
The HTPC is connected to the TV with an HDMI 2.1 cable. The soundbar is also connected to the TV, using an HDMI 2.1 cable.
The situation is more complicated for home cinema systems using a projector. In this case, the graphics card of the HTPC must have two HDMI outputs: one for the sound (it goes to the soundbar) and the other for the video (it connects to the projector). In general, for systems using a projector it is always preferable to use an AV amplifier,
There are several soundbars out there. Search the internet, study their features and select the one that fits your needs. Prices range from really cheap ones, 30-40 euros, up to few thousands euros.
Expect to pay about 1500 to 2000 for a good set (soundbar, surround speakers and subwoofer). Modern systems are wireless, and incorporate Alexa or Google Assistant.
I prefer the Sonos ARC combined with Sonos One and the Sonos subwoofer.
