Hi,
When I watch liveTV on France 2 HD, it all works fine (except for
core dump on exit, see below). But if I schedule a manual recording,
then the recording doesn't have any audio. Even if I watch it while it
is still recording. If I record from liveTV, then go and watch the
recording as it still records, I have sound. The symptoms are the same
either when watched on the backend or a frontend. It really seems to be
related to the manual recording; but given that there is no on-air
program, I can only record using manual recording.
This only happens on some HD channels but is consistent. When it
happens, there is no audio menu available.
France 2 HD has the following characteristics based on MythTV :
E-AC-3 Dolby
5.1 audio
H.264 MPEG-4
1080i HD
It works correctly on Arte HD, though sometime the sound hiccups when
there is music playing. It has the following characteristics:
MP2 MPEG
Stereo Audio
H.264 MPEG-4
1080i HD
On the back-end server, when I exit from watching this channel
(France 2 HD, LiveTV) or a recording on that channel, then mythfrontend
always crashes after I exit. But it doesn't fail on a frontend running
the nearly same version of Linux connected to the same backend.
Linux frontend 3.8.0-26-generic #38-Ubuntu SMP Mon Jun 17 21:46:08 UTC

Linux backend 3.8.0-25-generic #37-Ubuntu SMP Thu Jun 6 20:47:30 UTC
2013 i686 athlon i686 GNU/Linux
I just upgraded to the release below and I get the same results.

On the backend, I'm connected using HDMI to the TV and the audio is
using the stereo output of the PC to the home cinema. On the frontend,
I'm using a DVI output and stereo speakers.
So what can I do about this?
