I’ve upgraded to PMS 1.7.2 on my WD PR4100 and tried recording a TV program, at HD, and there seems to be no audio. I’ve checked the .mkv file with mediainfo and it tells me there is NO audio channel! What am I doing wrong? This used to work OK only the other day.
P.S. PMS used to record TV in .ts format now its in .mkv. Is that something to do with the lack of audio?
It shouldn’t, go ahead and give me logs for Plex Media Server and Plex Tuner Service and we can look to see if it says what happened, but thats concerning.
When I looked at this last night I’m sure mediainfo was showing NO audio channel. Now its showing a 1602 audio channel, whatever that is, and a bit rate of zero. I’ve attached a screenshot of mediainfo. I’ve also attached server logs. The recording in question is at 11.25pm yesterday UK time. It was of a film called Sliding Doors. I hope this helps. Let me know if you need any further information.
EDIT: Whilst VLC and Flims & TV from Windows store won’t play the audio PMP web does?!?!?
So at least you can watch it in PMP web. 
Well yes. But it would seem that there’s something wrong with the output file format. I originally thought that there was no audio channel but I now think this was due to my looking at the file, with mdeiainfo, before the recording was finished. Again, using mediainfo, the audio channel is reported as 1602 at 0 b/s. Seems strange to me and VLC and Windows player won’t play the file.
Specifically to manipulate TV video files recorded by PMS I bought some new software called VideoReDo. In processing the .mkv file VideoReDo crashes towards the end. I chopped off the end and managed to finalise converting the file. However, VideoReDo reports a huge number of audio frames dropped - see attached screen grab.
Basically, I’m concerned that the recording of TV files in the new PMS does not conform to standards. For .mkv.
I’m more than willing to provide additional information if that will help.
We don’t touch the audio, we remux, which means we pull it from Over the air and only changing the container format (from TS to MKV) so if there’s error, it’s what how we get it.
With that said, we’ve identified an issue with PMP and are looking into fixing it. Enabling ‘transcode on the fly’ might convert it to normal AAC (instead of AAC-HE aka AAC-LATM) which might help. It’s a setting in the dvr or tuner configuration.
