I replaced my Denon X4400H with a Denon X4500H and now have a working eARC configuration... however I have run into the limitation with PCM audio not working over the C9 eARC connection. As this should be a relatively easy fix for LG to support these sound formats I am chiming in that us owners really want to see this addressed soon in a firmware update.
I love this TV but I'm very frustrated by the lack of PCM audio over eARC. When you buy a $7000 TV you expect all of the advertised features, including eARC, to work correctly. I really hope LG will fix this in a firmware update. It will effect how likely I am to buy LG TVs in the future and whether I would recommend them to a friend.
For LG to simply miss the implementation of 6 and 8 channel LPCM is mind boggling. Unfortunately, I just bought the C9 and I'm now thinking of how to return it. I really hope there is some response to this soon.
They won’t fix this, they will use it as a feature to sell us a new TV next year. I bought this TV hoping to be ready for PlayStation 5 next year, but it looks like as forward facing as it may be, it’s still not ready for the future. I absolutely must have 5.1 LPCM through eARC so I can get my 4k @ 120hz from the PS5 and still have my lossless surround sound. I have a couple more days before the return window is up, so I’ll probably pack it up this weekend. Too bad because I really enjoy the TV, but I can’t buy a new one for the PS5 next year. It’s not reasonable. Maybe the C20 will be the one finally.
Just to avoid confusion: I also tested the eArc of the c9 and I have tested spoofing the edid with an HDFury Maestro device (which is also the eArc client). Wether the source is a PS4 Pro or Apple TV here, I get the same effect: only FL and FR are forwarded when the TV eARC mode is set to "auto" or LPCM. The TV also has a setting to support bitstream forwading but in that case there is no sound at all. So in neither case, also not with the help of a HDfury box LPCM 5.1 or 7.1 over eArc can currently be enabled. A more comprehensive fix then only adjusting the edid is required. I am also a customer who waited for the C9 (as opposed to the C8) to use the new eArc feature, assuming LPCM 5.1 would be included. So LG development please fix this, only then the TV is the best TV ever (and one could argue eArc is currently not fully implemented).
I am really shocked to discover this. I just got an OLED55C9. One of the main drivers to upgrade was eARC for sound from my PC (PC->TV->X6500H), but now I discover it can only do stereo from a PC. Truly awful omission.
When do we think it will be fixed. Might have to return my TV otherwsie
I just got the OLED65C9 and found out the hard way that multi channel PCM pass through isn’t supported via eARC. This is unfortunately a deal breaker for me so this TV will be returned and I’ll get the Sony A9G which supports this flawlessly. It’s really a shame, as besides this issue the TV is outstanding...
I would like to use my Xbox One X connected to my LG C9 TV and then eARC to my AVR. I cannot do this with the desired LPCM, as this LG issue has not been fixed.
As a new owner of the LG C9, I too am frustrated at the lack of proper multi-channel LPCM support. You'd think that after spending a small fortune on this equipment, proper LPCM support would come standard in 2019. This issue alone prompted me to research the matter online which ultimately led me to several online forums where many other C9 owners have voiced the same issues. I then decided to create an account on this forum and post this comment in effort to add my name to the growing list of owners who want this remedied ASAP. I hope that LG provides a response and a proper fix (firmware) to this sooner than later as I can't currently utilize my sound system to it's full potential. Unacceptable.
I too bought the LG C9 in large part due to the eARC support, hoping the TV would last as long as my panasonic plasma did (~10 years). Having waited over a year to make the jump to OLED and justifying £3k as a long-term investment, it is concerning that LG have been quiet on their intention to fix the issues...am I going to have to replace this TV when the PS5 comes out?
I hope LG can provide something concrete soon, as I am not likely to recommend them currently. I understand that Jamal is not going to want to post as currently they are informative but definitely not helpful.
Well I don't know how LG as a company internaly works but I do find it quite odd that a community manager asks the dev department about an issue and doesnot get any message back after more or less two month of waiting time.
So I guess all we can do is to inform as many people we can about this issue...
Indeed. This is strange. Maybe they are working on the summer update that brings 4K@120 + HDCP 2.3. At least that is the only plausible reason. But still... at least a small response from the devs would have been nice.
@JamalofLG, any possibility that you could again reach out/inquire with LG's engineering department for correspondence? All we're asking for is acknowledgement as these limitations/issues are obviously a widespread problem.
If you are in a country with good consumer protection laws you may be able to return/replace the TV if you bought it on the basis of advertised/announced features that do not eventuate. I will look at these options if eARC and BFI are not fixed before next year's model comes out, as without them there is very little to recommend the C9 over the much cheaper C8 for me.
I see this as a fundamental feature for a TV at this price. I was planning on updating my old Sony Bravia to a C9 but if this isn't resolved in a couple of months I'll be forced to look into Samsung or any other brand. For me, this "mistake" is absolutely inexcusable for this TV series
OMG 3 months passed and there haven’t been any report from an engineering team. What a shame, LG . If this issue isn’t fixed soon I’m going to buy Sony oled
BEYOND disappointed with my purchase of the LG C9. Audio lag with every single device i have connected via eARC (Xbox, PS4, Nintendo switch). It's unusable. (For ref, i have the Samsung Q90R soundbar which supports eARC audio).
Utter waste of money currently.
I will be returning this if this isn't sorted soon, and going with a competitor.
