HDMI (4K)-audio-extractor / HDMI to I2S
as i yesterday connected my (Sony) blurayplayer via coax to the Sanskrit i saw only „44 or 48“ at the display, means the player downsample all content to this rate (to coax/spdif) because of copyright issues/or technical limits in other cases.. (uargh..) ; you get only 192/176khz or 96/88khz via HDMI..
(btw. nice description of this „case“ is here->“The extractor overcomes the restriction the visual media puts on its audio – namely restricting it to HDMI – by liberating it from its HDMI cell and forwarding it in a freed state…“->https://community.naimaudio.com/t/hi-res-audio-from-visual-media-sources/10673)
okay, and so we need a „HDMI (4K)-audio-extractor“ (see other post before->http://essabre-90xx-rpi.sfb2.com/?p=2477) (i originally wanted this extractor for the „I2S-line“, see at the bottom)
there are a ot of them around, beginning at 20$ (up to 60$ or more)(this for example)->https://www.lindy.de/HDMI-4K-Audio-Extractor.htm?websale8=ld0101&pi=38167
very important seems also the „ARC“-function + EDID-support/settings (will post maybe then more about it)..
obviously its better to buy directly a HDMI-extractor with I2S output to „bypass“ the spdif-conversion (and as we know „our“ early chinese ES9038Q2M-boards had not such a good „coax/toslink/spdif-line“ (the first onboard spdif-receiver-chips were not soo good (hashtag #SRC4192/AK4113/4118) ->http://essabre-90xx-rpi.sfb2.com/?p=2211 ->“..First, on the new, blue SMPCB they use some „DS9281“ for „better coaxial conversion, less jitter, less „lock“-„problems, „better coaxial line..“)->
(50$/37$ Aliexpress->https://de.aliexpress.com/item/1005001265826217.html ;https://de.aliexpress.com/item/33031920347.html , same one from audiophonics (66€)->LINK))
i guess i´ll start with a „cheap“ one from aliexpress (Link is coming..) ..
many greets for now !! 😉
