[SOLVED] SMP-N100 - MKV MP3 No sound

Hi all,

I've only just stubled across this program as I have been using Windows Media Player previously (with less than great results!). I was very pleased to see that I can now play even more of my files than I ever could before.

I was hoping I could get some advice on 1 issue that I'm having - I downloaded a file every other week (Motorsport) that comes down as a MKV file.
It seems to play the video just fine but there is no audio.

I tried some of the Profile hacks that I could find but nothing seemed to help.

Any help greatly appreciated!

I used Mediainfo (after I did some searching on here I saw this mentioned) and it lists this file as

I should add that when I play this directly on the device via USB I get video and audio but it plays with a stutter.

I have a similar problem playing files wirelessly. I thought the problem was the bitrate over the wireless network. It might be the smp-n100 can't handle that fast a stream. I changed the profile to always re-encoding the mkv files and down grade the video stream bit rate and set it to 720p. viewtopic.php?f=11&t=6591

hope it helps

SOLVED!
