The following fixes the audio switch problem for me:

diff -uN vdr-1.1.13-orig/dvbdevice.c vdr-1.1.13/dvbdevice.c
--- vdr-1.1.13-orig/dvbdevice.c	Sat Oct 12 13:15:45 2002

 void cDvbDevice::SetAudioTrackDevice(int Index)
 {
   if (0 <= Index && Index < NumAudioTracks()) {
-     DelPid(pidHandles[ptAudio].pid);
+     //XXX DelPid(pidHandles[ptAudio].pid);
      AddPid(Index ? aPid2 : aPid1, ptAudio);
      }
 }

The problem seems to be, that DelPid() closes the demux
filehandle if no one else uses the PID. This seems to disrupt the
decoding.

Don't try to switch the audio while recording, this will ruin
your recording. I don't see a easy solution for this, may be we
should disable audio switching while recording on the primary
interface?

I also noticed that switching the audio stream doesn't works, if
you are watching a channel in transfer mode. Is this intended?

Klaus?
