Losing Audio after certain amount of channel switching

[saitoh183]

I just finished configuring NPVR back on my system and everything seems smooth for the most part but i noticed in Kodi that when i go to certain channels the audio would not be on and the video would stutter. So i tested in the NPVR client and i get that after navigate to different channels randomly (stay on each channel a few seconds) i will eventually loose audio on a channel a change to and when i right click and check audio stream, there is nothing but viedo is playing with no stutter. Here is my logs and config file

There isn't anything obvious in the logs, but if it happens in both apps, it sounds like it's some problem with the audio being produced by your Colossus.

I'd first start by copying one of the live tv buffer files when the audio is missing, and try playing it in other players like VLC, to see if the audio from the Colossus is fine or broken.

If the files themselves are fine, then it must be playback issues, so look at the decoders you're using in NextPVR (and Kodi may have some playback settings you need to change).

It seems that not all your channels are coming out in digital AC3 and sometimes the resolution changes and sometimes it doesn't (but it looks like you have fixed 720p)

@mvalleand

Yes, The ones that are AAC are when i get no audio. But i dont know why it changes all of a sudden. As for the fixed 720p, I set my set top box to only 720p to avoid large TS files and bandwidth issue when try to stream over wifi back when i had Kodi on a wireless box but i dont know if this could be the reason im having this issue.

@sub

I will give it a try. Im using the Lav codec from the SAF bundle
