It depends on your box. Press pause, play or yellow button. Then video should stop. Wait some seconds and with pause/play you start playing video.
Do you have linux?
Or better: Can you make a short recording (only 10-20 seconds) and post it here? If you don't want to publish it here, you can send it me via personal message.
Hi there!
The audio is OK in time shift mode! The audio PID is 1224 & the video PID & PCR are 1024.
