Hi,
I have sound problem when I use Alpha MX _Player on my Tronsmart RK3288 (Kit Kat android) to play AC3 movies.
My receiver can play correctly the Dolby sound but there is white noise on the TV speakers then I have to mute the TV sound.
It's a little bit annoying if I forget to mute the TV.
Do you have any hint to help me to turn off automatically this white noise on the TV ?
Thanks in advance for your help

I am not sure what happens exactly.
Have you connected your audio receiver on S/PDIF...?
Does it happens with other video files which doesn't have ac3 or DTS...?
What I suspect is your device pass the audio stream to both S/PDIF & HDMI (TV). Your receiver can decode it since it has proper ac3 decoders. But, Your TV might not have ac3 decoder & produces unnecessary noise when failed to decode the stream.
Does your TV Player have native video player..?
Probably when you play the same video there you will encounter the same issue.

Thanks a lot for your help.
Sorry to forgot to describe my setup:
First Setup:
Tronsmart Box (KitKat) -> TV via HDMI
Tronsmart Box -> Yamaha receiver via SPDIF
Android Sound Manager: set to SPDIF
Second setup:
Tronsmart Box (KitKat)-> TV via HDMI
TV -> Yamaha receiver via SPDIF (My TV has SPDIF output)
Android Sound Manager: set to HDMI Bitstream
Both of the above setup have problem of the TV Speaker when playing DTS/AC3 movies.
TV does not have sound problem if playing non DTS/AC3 movies.
I will try the Tronsmart native player tonight and will let you know.
PS: I don't have TV sound problem with the same setup for other box with Lollipop but have subtitle delayed problem
Thanks again

When you set audio out to SPDIF audio not suppose to be passed. Am I right..?
Do you get audio on TV when you play a video with other audio codecs..? In the above setup there shouldn't be any audio.
In simple words, I wonder why TV is making noise when audio is not passed to it.
Regarding subtitle delay issue with another device, does it happens with HW+ or SW...?.
Anyway MX has default subtitle sync options for all decoder ( & HW decoder separately if you only has issues with HW). You set it once & enjoy rather than adjusting everytime.

When I use the Wireless Display feature of Cast, it's not passing sound through to my TV. The video displays on my TV but the audio plays on my phone.
Hi all.
I wonder if I can stream Bluetooth to Android TV boxes same way as with Bluetooth speaker? I'm looking at Xiaomi MI Box in particular: I have stereo receiver with optical, and want to use it for streaming. I might just buy Chromecast audio, but I have some screends and might use it for video as well.
Pretty much I want chromecast audio with Bluetooth abilities. Can anyone try streaming music from phone to Xiaomi box?
Thanks.
When I have my phone playing music over bluetooth and have it streaming to my Chromecast the phone will disconnect from the bluetooth device whenever the Chromecast finishes playing its queue. Is there any way to get this to stop? This also happens If I turn off the TV to end the cast.
Is it possible to mute the TV while listening via cellphone earbuds or headphone?
