Audio goes off 1 second, but video plays perfect

Hello.

Im having troubleswith some video files, specially on MKV or heavy files.

For example playing Avatar 1080p DOLBY AC3. THe video plays perfect but sometimes the audio goes off for 1 second and returns, I dont know why this happen.

I would like to know how to fix this. And why this can be happening. I tried a diferent media server Like Wild Media Server, and the same happens.

I love Serviio but I really want to play AC3 or DTS files, wiuthout problems.

PS: PCM audio (Stereo) plays better, but sometimes the audio goes off for 1 second. But in DOLBY or DTS the audio goes off very often and not so much in PCM video files.

I really appreciatte the help. The TV model is Samsuns PL43E490 with the last firmware.

The file is not transcoded, so it's either dodgy file or the TV doesn't cope with the high bitrate. The fact that it's the same on the other server supports this.

I see, so what is the best solution for this?

What should I do?

Thanks for your help
