.. using native player or kodi player?
.. did u play with subtitle advance/delay option?
.. what audio system - tv, avr, soundbar?

i hv played 6gb to 66 gb files and not experienced anything u mentioned! the file just 30GB+

maybe that file of yours bad, corrupted..? or all files like that? All video play fine. It only happen after playing video more than 3 hours


what is interesting is this u said:

Audio keep looping when changing the audio from 7.1 to 5.1. (.MKV)

what file is this? how big? mkv or mt2s? hevc? 10 bit? MKV with multiple audio inside..  Multi 2160p 4K UHD Bluray HEVC10 SDR Dolby Atmos 7.1. Inside have 5.1 audio also.


maybe the soundbar is causing trouble..?

using soundbar...
..how is it connected.. hdmi or optical or coaxial? Optical to tv, q10Pro direct hdmi to TV
..how does 5.1 and 7.1 sound like.. i thought it's just 2.1?! It just sound louder at 5.1. I am not talking about the effect. My question is why it loops?

disconnect the soundbar, just q10pro->hdmi->tv, i.e. tv audio... play same file , see what happens. May i know what is the different since I connect q10pro direct to the tv then optical send audio to sound bar?
nicety... maybe u hv some comment...

ah yes... the tv can be an issue. Vinration doesn't happen with TV setting menu. But the tv box launcher 

some smart tv's occasionally can't cope with certain input, will stutter, need reset... i hv seen that.

The strange is the launcher(home) screen is vibrated as well, therefore I eliminated network and NAS factors. For the moment my recommendation is to reformat the box via the recovery button to isolate if due to software or OS. Ideally iif could test with another TV with different HDMI cable then will be able to isolate other factors as well.

unless the file u have is a short one, i doubt with such heavy specs it is as small as 30gb.
it should be >50gb, more likely 60-66gb.
hence, i suspect the ripping of that file is not well done.
u can try the same title but a diff rip, similar or bigger size and see if it is the same.
you can also get a diff similar specs file and try it, see if same problem occurs.

the audio part... i suspect the problem is coming from yr tv ARC.
for yr set up, it is better to have optical or coaxial audio output from q10pro direct to soundbar.
if u do tv optical back to soundbar, u are using the ARC function of the tv.
some devices do not work well with some tv ARC's and are known to cause problems.
also, tv ARC capability is typically not of high standard, may not cope with HD audio well - TV makers focus on video, not audio.

if u disconnect the soundbar, u isolate it.
then u can see if q10pro->tv hdmi video and audio eliminates a possible problem caused by soundbar and/or the tv ARC.

similarly, if u do q10pro audio->soundbar, audio is now independent of the TV.
so, if the audio loop problem persist, u know it has nothing to do with the tv or tv ARC.
if that solves the problem, u know yr tv ARC isn't good enough to handle HD audio.

bit by bit, u can narrow down the root cause(s)!

After recovery, pls don't install any apps. Direct test the vibrate issue with your movies. As mentioned, test the movies directly from pendrive or USB HDD.

please report back if i was right about the audio bit!
