I can reproduce this if I do the following:
- start an instant recording (with DO_REC_AND_PLAY_ON_PRIMARY_DEVICE 
  disabled, so transfer mode is disabled)
- stop recording
- try to replay this recording immediately
current channel is being displayed, audio muted
- stop replay
- start replay
now everything is fine

It seems to be an issue with the correct sequence of ioctl calls,
especially the VIDEO/AUDIO_SELECT_SOURCE appears to be critical.

As a fix, I'm currently testing this patch:

Sorry Marek, this will probably not solve your problem...
