HDMI (4K)-audio-extractor / HDMI to I2S

so, 😉

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..”)->
