jkcs Posted May 27, 2021 Posted May 27, 2021 (edited) Hi all, Allow me to rephrase myself, sorry for the confusing first post I have a new Samsung smart TV with built-in streaming apps like Netflix and Disney+ etc, I only wanted the sound to pass thru the AVR to get 5.1 channel, but failed. (My new TV eARC port is only HDMI 2.0b according to some TV reviews website.) - sound is distorted, even if the source is TV, the result is the same. My connect as below: TV(eARC) -> AVR (ARC) - all using existing HDMI cable - Used a new HDMI 2.1 cable and gotten the same unsuccessful result. - TV settings for "Sound" menu has not much option to change to Edited May 31, 2021 by jkcs edited "Title" and post to express my problem more specific
rayleh Posted May 27, 2021 Posted May 27, 2021 If you are looking for uncompressed sound formats, you have no choice but get an AVR with eARC

Boxerfan88 Posted May 27, 2021 Posted May 27, 2021 (edited) How is your TV sending audio to your AVR now? Optical cable ? Edited May 27, 2021 by Boxerfan88

jkcs Posted June 2, 2021 Author Posted June 2, 2021 sorry for being so shameless. haha Anybody here as similar experience or setup that works? my TV is a Samung Q60A and a Denon 1911. Technically HDMI is backward compatible as I done my studies on the internet. It is just that I don't want to buy a new AVR to find out root cause isn't from the old AVR. tyvm
petetherock Posted June 2, 2021 Posted June 2, 2021 You’ll need to share more on your setup and maybe record the sound bro. I don’t think it’s your amp.

Maybe you could elaborate more on what distorted sound meant. Can you still hear the sound correctly, like the dialogue, or it is just you do not get the sound effects expected. 2. Will you be able to connect other source to the another HDMI port or a notebook., then I guess you could determine whether it is the AVR that is causing it. 3. Or you could use optical from TV to the AVR to see whether that works. Hope it could help Thanks

Hope it could help Thanks Hi Petetherock and wcseow, 1) My TV and AVR are connected using HDMI cable via eARC and ARC port respectively. I just want the native apps e.g Disney+, Netflix to play 5.1 channel thru my HT. 2) Samsung Q60A tv only support Dolby Digital + 3) Cannot select "Pass-through" under Expert settings for sound mode in TV, see "TV sound settings.jpg" 4) If playing from Netflix/Disney+, the AVR detected as Dolby digital + but the display looks weird and the sound output is distorted, see "TV_netflix.jpg" a) if I changed the sound settings to PCM, the LCD display and sound output is like point 5 below 5) If playing from Youtube, the AVR detected as "PLII" , but the sound is only 2.1 channel, see "Youtubejpg.jpg" thanks so much for replying to my qns, appreciate alot

It seems to say only HDMI sources can be routed via eARC. Does your TV support sending raw audio from apps (NFLX/DSN+) in a passthru fashion via eARC? I donno…. Edited June 3, 2021 by Boxerfan88
petetherock Posted June 3, 2021 Posted June 3, 2021 Try "Auto" bro.. Just cycle through the various options to see if the sound gets better. Your AVR should be able to decode the regular bitstream / PCM options.

I know it can decode (or whatever the term is) Dolby Digital +. this is written on the product spec in samsung TV URL. Samsung is so green that it does not print user manual in hardcopy anymore.
Guest wcseow Posted June 4, 2021 Posted June 4, 2021 Sorry for being repetitive, 1. Could you explain what do you hear when you said distorted?.....for example can you still make out the dialogue. 2. In your earlier post, you mention when Youtube is played and PL II is displayed on AVR, is the sound ok? Thanks

Samsung is so green that it does not print user manual in hardcopy anymore. maybe i can suggest to try another way, out of band method. if your tv got optical out, use an optical cable to connect from tv to avr. configure tv to send raw audio via optical. configure avr to receive audio via optical. if it works, this could be your workaround… Edited June 5, 2021 by Boxerfan88
petetherock Posted June 5, 2021 Posted June 5, 2021 Yeah if optical works it may not be the encoding and the fault may lie in the HDMI part

petetherock Posted June 5, 2021 Posted June 5, 2021 If there's a mode where the sound is clear, then it's unlikely to be your amp / speakers. Then you'll need to work out the signal that's sent to your amp. Since we don't know that, you just try a few settings, and using trial and error, you may succeed.

The issue you are facing is not HDMI 2 vs 2.1 port or chip compatible , that is why you connected your New Tv to the older Denon is still will work. But the problem you face is eARC vs ARC , take a look on the Question and Answer , there are more inside the chip and cable , like network/ CEC etc....Lor Edited June 5, 2021 by econav
Raylim76 Posted June 6, 2021 Posted June 6, 2021 Allow me to make this clearer. Correct me if I'm wrong with my understanding. I think what jkcs is trying to say is regardless whether HDMI 2.0 or HDMI 2.1, all HDMI connection is "backward compatible". This is NOT wrong. For eARC (HDMI 2.1 specs) vs normal ARC (HDMI 2.0 specs), this may be a little tricky as it really depends on the manufacturer's intent to make their products to work with both eARC and ARC seamlessly. With all intents and purposes, I'm pretty sure jkcs is fully aware that HD lossless audio like Dolby Atmos and DTS-X cannot be output to his old AVR (which only support ARC) since he emphasize in getting normal 5.1 sound output and never once did he ever mention about lossless HD audio in the likes of Dolby Atmos or DTS-X. So he is NOT wrong to say that it should be able to get at the very least, Dolby Digital + or normal DTS Core format to work since HDMI 2.0 and HDMI 2.1 specs (with ARC as a subset) are backward compatible. The AV device (equipment) we use - i.e. TV/display and Amp/AVR should be able to "auto-negotiate" among each other while still using one medium - i.e. HDMI cable. I have no answer as to why jkcs is experiencing "distorted" sound on his system while connecting using a typical HDMI cable while he have no issue with Youtube playback (sound is fine) while connection remain the same in both scenario. @jkcs - Can you use other HDMI port on your Samsung TV which has no eARC label on them or are all the HDMI ports eARC-compliant?
jkcs Posted June 8, 2021 Author Posted June 8, 2021 (edited) @econav, actually I am a noob in this area, in fact in other area also, so my understanding might be wrong after reading some articles via Net. @Raylim76, u completely understood my intentions despite some bad terms I used to describe my problems. maybe next time i buy AVC-3700H because its product description mentioned the below. Enhanced Audio Return Channel (eARC) HDMI support: Through the main HDMI output, connect your TV with eARC HDMI support to allow uncompressed and object-based audio formats like Dolby Atmos and DTS:X directly from your smart TV app to your AV receiver.

Have you tried a clean power reset?ns E.g. power off at the mains and disconnect the power chord from the unit. Wait for a short while and then reconnect. If it does not resolved then may be can consider doing a factory default.
jkcs Posted July 2, 2021 Author Posted July 2, 2021 I am thinking of relaying new speakers wire that is hidden inside my false ceiling for the surrond. I think to do this, need to open up some parts of the partition and reseal when completed. Any bro here as contact/lobang to recommend? my bad, I lost contact with my reno contractor already (more than a decade since engaging him) . I have messaged some handyman in carousell, pending their reply. Do share contacts if you know..
