[vdr] Sound problem with channels with 2 Apids

["Olivier Kojack" <mydvbs@hotmail.com>]

Hi there.
First, congrats for vdr, this is an excellent job (and the sources are 
sooooo clear :) ). I'm just trying to explain one of my problems here and 
request for help, while I'm trying to fix the issue by myself also...

I've been observing a problem with channels that have 2 APid (like Kiosque 
on Astra).
I'm running vdr on Mandrake 8.2, vdr 1.0.2 + aio 12/05, dvb drivers 
2002-04-01.
When switching to those channels, I get a strange sound, like if the 
demuxing was bad.
I have searched and somebody detailed on a forum a workaround which is to 
press Menu/Language (green button) twice. Actually the sound is ok the first 
time I press it, but this is not the language I needed :)
Another thing (as far as test goes): I can record a channel that sounds bad 
and replay it without any sound problems this time. But the problem is back 
each time I switch to the channel.

I tried to investigate and found (in dvbapi.c) the function that is called 
at the time I press "Menu/Language": cDvbApi::ToggleAudioTrack(void), which, 
in turn, calls SetPids where APids are set.
In the cDvbApi::SetChannel function which is called each time a channel is 
tuned, the cDvbApi::SetPids function is also called. Here is the content:
  return SetVpid(vPid,   ForRecording ? DMX_OUT_TS_TAP : DMX_OUT_DECODER) &&
         SetApid1(aPid1, ForRecording ? DMX_OUT_TS_TAP : DMX_OUT_DECODER) &&
         SetApid2(ForRecording ? aPid2 : 0, DMX_OUT_TS_TAP) && 
(!Setup.RecordDolbyDigital ||
         SetDpid1(ForRecording ? dPid1 : 0, DMX_OUT_TS_TAP) &&
         SetDpid2(ForRecording ? dPid2 : 0, DMX_OUT_TS_TAP));

Can it be a problem that we set Apid2 only if we record?

I found also in dvbapi.h the following lines:
  bool SetApid1(int Apid, dmxOutput_t Output) { return SetPid(fd_demuxa1, 
DMX_PES_AUDIO,    Apid, Output); }
  bool SetApid2(int Apid, dmxOutput_t Output) { return SetPid(fd_demuxa2, 
DMX_PES_OTHER,    Apid, Output); }

Is it normal that for SetApid2, we use "DMX_PES_OTHER"? Might be, but I just 
don't know :)

Well, I tried to change around this and didn't fixed the problem.

Has anybody any other idea?

Thanks!
