That may be bandwidth or CPU related. If your files are on the LAN, try local files.
MC's DLNA server has conversion settings you could try. It's under Media Network > Add or edit DLNA servers.
Greetings:
This Asus server is windows 10 64 bit. I have around 2015 with dual boot Ubuntu 15.10 64 bit installed MC 21.16, MC 21.23, with no audio video issues for two months.
Core i7 3.47- Ghz, 16 gig of memory.
I have wired and wireless . On this Asus, my wifi speed clocks at 866 M/bs, wired is 1000M/bs.
Someone suggested, we need look ahead buffer for movies, this may be the trick to solving this audio cranking up.
In addition : This A.M 09/16/2017, same Windows machine, I went to adjust in Audio > Device setting > I moved the controversial "slider" from the default to maximum:
Please read the results below:
The Mummy 1080P ripped mkv I watched the entire movie... no audio or video glitch. Last night, audio issue was audible video was also breaking, but very minor.
Alien Covenant 1080P ripped mkv I watched the entire movie... no audio or video glitch
Assassin's Creed 1080P ripped mkv I watched entire movie, no audio or video glitch
Celine Dion A new Day 1080P ripped mkv.. same, no glitch
It is looking like the slider moving up to maximum position is the "fix" for this audio issue.
Too bad the slider has no numerical fields attached to this, so I am not able to use this to fix same issues on the Linux 64 bit version.
Windows version has more tweaking and flexible options compared to the Linux version.
At the conclusion of this writing, I m going to adjust the Audio Device setting, and set the slider at the default position for comparative testing again. I bet you the issue will pop up again.
I have tried all the conversion settings
Thanks.
George
