It seems to be a downmixing issue with the sony TV. Could you please set force stereo downmixing in nova settings and see if it helps?

yaswanth127 commented 2 years ago

Downmixing does loss the atmos data right?

Yes but please report the result. And your comment indicates that you are not using the TV loudspeakers. Are you using a soundbar or AV receiver? If this is the case please let me know how the connectivity is set up.

I am using Tv speakers

Thus you are in stereo and require downmixing. TV should do it automatically on multichannel but perhaps for some reason it does not.

But I am getting good audio in normal media player??

Any video player will downmix to stereo. Nova trusts the platform to perform the downmix. It does not happen thus you are loosing front channels resulting in poor sound. Forcing downmix in nova should restore the missing channels. Can you please try my suggestion, compare sound with "normal media player" and report any difference?

yaswanth127 commented 2 years ago

I have tried and the volume looks normal but no changes in surround or dialogues as we are controlling in system settings. The sound from player is independent of the system.

Now the next test is to disable "force downmix" and enable in nova setting passthrough mode 2 and check if it improves simulated surround effect on stereo speakers of the TV.

yaswanth127 commented 2 years ago

For dolby digital, the mode 2 seems okayish but resulting in audio sync issues

Actually the sound is very good in mode 2, but audio sync issues are high

Any update on this issue, will it be fixed anytime soon?

courville commented 1 year ago

I see that your TV takes dolby atmos and dts sound input. I see that even with 2 speakers, the TV has some 3D audio processing capabilities:

XR Surround With BRAVIA XR, everything you watch gets the true surround sound treatment. XR Surround creates surround sound from the sides and vertically so you can experience 3D audio without the need for in-ceiling or up-firing speakers.

Nova should provide 5.1 output passed to Android and processed by the sony TV correctly even in non passthrough mode using multichannel PCM and the sound should be good. Perhaps the TV applies the XR effects but not on PCM 6CH outputs which would explain the current behavior.

It will be difficult to investigate further without such a TV.

Could you please check this experimental build without any audio passthrough selected and report if it helps? https://drive.google.com/file/d/1QzWksWwcM4A2spdPXOH9RqO7dGcoeNQ4/view?usp=sharing

EDIT: just updated the apk to also capture truehd

mindstop commented 1 year ago

Hi Courville, I tested this new build on the Sony X90K, the audio is still low without any audio passthrough. But on mode 2 of audio passthrough, the audio is much better. Downmixing doesn't help either. Even with audio passthrough (mode 2), it still doesn't beat the built in player. Let me know if you need any other details.
