Hello, I'd like to ask question about playing Atmos movies on my computer using Potplayer + LavFilters + Madvr.
My Lavfilters has been upgraded to 0.75.1-43. My power amplifier is Marantz Sr7013 and 7.1.4 speakers.
1：When TrueHD is checked, the original sound data 4800hz 24 bit - > is converted to 19200hz 16 bit, which can light up the power amplifier Atmos. Is this the original Atmos data? Has the sound quality decreased?
converted to 19200hz 16 bit amp shows Dolby Atmos

2：When bitstreaming format is unchecked, Atmos decoding is lost and becomes 7.1 channel 4800hz 24 bit or 7.1 channel 4800hz 32 bit.
With the same Atmos track and different settings, the three sounds are compared.
Atmos 19200hz 16 bit sound is relatively small, not lively enough, and the dynamic feeling is small. But there is more sound positioning.
7.1 channel 4800hz 24 bit = 7.1 channel 4800hz 32 bit, louder sound, more lively and dynamic. I like the sound instead, but there is no Atmos.
I wonder. Why are these options so different?
