Tvheadend

Occasionally when watching a channel live that the DVR is recording, I will get no Audio. If I stop, and go back the missing Audio continues. Once it happens it always continues until the recording stops or I manually interrupt the pipe so the MPEGTS stream restarts. It can happen on a few different channels/muxes from the same source. However while I get no audio to my htsp client, the dvr records the audio perfectly in sync and can be played back later from kodi or directly with VLC. DVR is recording with pass. This also happens on many different devices and couple different clients

Im using streamlink 0.7 to pipe hls variant stream into TVH, as ffmpeg can't multi-tread grabbing segments and tends to get a lot of dropped streams because of that.

Im currently using 4.3-448 but I have noticed same thing in few past 4.3 builds.

This bug is impossible to reproduce on demand, just seams to randomly happen. However it seams more common when the dvr has been recording the channel for a long period of time. I am unsure if time is related or just the longer run time gives it a better chance of occurring.

I have been running debug all, and trace htsp log trying to catch it. I believe the line below is hinting at the problem as the only time I have seen it is when the problem happens, and is ALWAYS present when the problem is occurring.
