If you do not fully understand the latest top game consoles, here is a brief review of recent events. A few days ago, Microsoft introduced the Xbox Series X hardware in detail. Yesterday, Sony released its own presentation, detailing the upcoming PlayStation 5. This naturally aroused people's interest and discussion on these two game consoles again, and launched a series of comparisons. Early, incomplete specifications and information.
 A small detail that has recently attracted attention relates to the optical audio output (S/PDIF) interface. Some early Xbox Series X appliances (such as those shown in Microsoft's Game Stack Live demo) have indicated migration. Other known units do not. We can only assume that the specific technical tone of Sony's initial demonstration of PS5 streaming media to developers on GDC 2020 may have attracted attention to such details. In any case, IGN apparently contacted Microsoft, where officials confirmed that S/PDIF optical audio would not be available on Xbox Series X.
 Considering the current Xbox console and even the cheaper Xbox One S, it is a bit strange to say ports. On the contrary, the X series will rely entirely on its HDMI 2.1 port, which has enough output bandwidth to support video resolution at the same time, up to 8K and Dolby Atmos audio. Having said that, the lack of dedicated optical audio output is very unpleasant, or at least the reason for rewiring some customer settings. If you are currently using direct audio output from the existing console to the speaker system, and there is no receiver or modern TV in the middle, you will have to reconsider some work of the X series. Response: "Xbox Series X will include ports for network connection (Ethernet), HDMI output, Seagate storage expansion card and three USB 3.1 ports."
 To sum up, we are still not sure how PlayStation 5 handles its audio output. In its presentation, Sony boasted of the advanced audio function of the upcoming game console. Obviously, we can expect to get immersive 3D audio through the customized Tempest audio engine, and even make adjustments based on each user. Therefore, there are definitely many places to be untied on both sides of the roadblock.
 At the same time, we borrowed this beautiful form from IGN, which compares the specifications that have been published so far.
