Welcome,
After months of searching and traying I finally found solution for DD and DTS in "Kodi" by HDMI Bitrate and DTS HD-Master and Dolby True HD in MXPlayer
Solution:
1. You have to install "Z4_UGOOS_MOD_V1.5" firmware made by @Yablar.
2. Change in audio settings to HDMI Bitrate.
3. Delete default Kodi version.
4. Install "ugoos_kodi_20160620.apk" from ugoos oficial page.
5. In ugoos kodi SYSTEM settings (expert) choose transfer to output device on (or something similar) and all settings DD,DTS... to on. Don't turn on DSP.
6. In Video settings you have to turn off "Accelerate RKCodec" in "RKMC" tab because if is ON the video is not playing fluently.

Thats all. Have a nice day/night

Hi,

This is my post from xda

For me today the best solution is combination: Z4_UGOOS_MOD_V1.5" firmware made by @Yablar and the newest firmware Ugoos UT4 1.1.4.
How to flash i describe in different topic on this EKB3368 page.
You can choose ugoos 1.1.4 or ugoos 1.1.4 for Android TV (it looks like Nvidia shield TV software).
In this solution you have ugoos kodi version 16 from November 2016 and hd audio works superb.

Thanks lord_yabol could you provide me links to try out ugoos 1.1.4 for Android TV on my Z4. Appriciated your help. And Agreed Z4_UGOOS_MOD_V1.5 is the one best ROM so far.

it works and so far looks solid. Specially Kodi is good.

one can not have a stock firmware updated and ready for use without having to make changes after the installation?
I see that almost all of the firmware they need to make changes after the installation, and unfortunately not everyone is able to make them!
I speak of stock firmware, and not of ugoos mod rom!
I have a z4 2g / 16g EKB368

Always read and confirm model before flashing. Number of posts regards Z4L having different WiFi chip.

BTW the above combo given by @lord_yabol is excellent. Thanks.

If you like the pro & cons of the google android leanback TV launcher, this custom rom should make definitely the race

Then just use the original Ugoos firmware posted on their blog with ethernet, that doesn't contain this bug.
Did you clear data or wipe from TWRP recovery or did a factory reset?

yes, i did. I can't use the original Ugoos firmware, cause my android box is a Z4 Rk3368. The funny thing is In ugoos 1.1.3 this error doesn't happen. Any solution? (I need the ugoos 1.1.4 because has fix for netflix sound).
Thanks in advance
