It seems like there is no full support for 5.1 or 7.1 LPCM audio on ports HDM1 and HDM2 on the HW-Q950T sound bar. Some people report that multichannel PCM is also not working fine via eARC, but I couldn't try this myself.
For sure, it looks like the EDID reported by the soundbar is only stereo 2.0 for PCM sources.
Is it possible to fix this and add multichannel PCM support to the HW-Q950T? HW-Q90R is perfectly compatible with multichannel PCM.
The soundbar does not support multi-channel PCM from any port, either via eARC or directly. This still stands even after the 1017.5 update.
This also means that you cannot play any video game using Atmos unless you transcode somewhere in the chain, as games use Dolby MAT which is metadata over multi-channel PCM. Previous soundbars were working perfectly.
They will not here. This is an echo chamber where no help is offered at all. They acknowledged it in my communication with Samsung Support in Germany, but only said they would report the issue to "HQ". Please please, contact your normal support. Don't expect anything from posting in here.
This is so disappointing. The Q70R was fantastic and I was so looking forward to getting this up and running. Now I feel robbed. Why on earth would you remove this feature in such an expensive bar??
Anyone reading this planning to use it on consoles, DO NOT BUY until Samsung have issued a fix as any games that only put out 7.1 rathe than Atmos will not work and you'll be left with stereo.
