It's because trying to carry audio and video over separate channels brings a host of usability and timing issues that just aren't worth the hassle (for the manufacturer or the user).Ĭlick to expand.The DVD player was manufactured September 1999. It's not just cost savings (although that may be a factor). There's a reason that devices like ATV4k don't have optical output. Even my seven-year old Yamaha AVR is more than sufficient for most purposes. If budget is really an issue, look for used items. Really it's not worth it in today's day and age. And sometimes there are no presets for that so you have to keep a sticky note and then change the settings every time you change sources. Otherwise you are going to have to manually adjust lipsync of each input device. It also has mechanisms for devices to self-report their signal propagation time. If your TV can't to HDMI ARC, that's okay, just hook things up via the AVR (the old fashioned way). If a piece of equipment can't handle that, donate it to Goodwill (or try to sell it) and buy a piece of equipment that can handle audio over HDMI. I learned that in the last few months.įWIW I am strongly opposed to any idea of an HDMI optical extractor. Would that be sufficient for the amount of audio information that runs over HDMI when 'extracted'?ĮDIT: I was looking at for instance the OREI HDA-912 4K HDMI Audio Converter.Ĭlick to expand.Until recently I didn't think that optical could pass multi-channel at all. According to the manual they can handle a signal that is "either a Dolby Digital signal, a DTS signal or a standard PCM (S/P-DIF) digital source". I'm not able to figure out what the bandwidth capacity of those inputs really is. ![]() That receiver obviously lacks HDMI but has optical and coaxial digital inputs. ![]() What I am wondering is if it would be possible to use an HDMI extractor to get 5.1 sound through the Harman somehow? This results in stereo sound only (though the Harman has that Logic 7 thingy that tries to mimic surround sound somehow). On the ATV 3 I used the optical out for 5.1 sound, but since the ATV 4K lacks audio out I am currently outputting audio from the TV's optical digital out. The surround system will be upgraded too at some point. Surround sound is provided by an old Harman Kardon AVR 130 and a set of Canton MX with sub. ![]() The sources are either ripped DVDs from our media centre or streamed movies and series from iTunes, Netflix and the like. The idea is to upgrade the TV at some point, but for now we use an old (but imho still quite OK) Panasonic HD plasma – the TX-P50GT30. We recently bought an Apple TV 4K to replace our Apple TV 3.
