Description

Hi,

Occasionally audio is missing in when starting a channel in kodi, this is an issue for quite a long time now but I thought it was kodi's fault.
Now, I saw that tvheadend is logging something exceptional when this happens.
-> parser: The timediff for MPEG2AUDIO is big (6066683), using current dts

This line only appears in the tvheadend log when there is no audio in kodi.

The problem reminds me to the no video issue back in the old days, maybe the same fix is needed for audio?

  • Subject changed from Occasionally no audio to 4.0: Occasionally no audio

Try latest 4.1 . It's unlikely that this bug will be resolved for 4.0.

#2

Updated by glenn ch almost 5 years ago

This issue is still present in master, it even feels like it's occurring more than with 4.0.
