Actually VDR tries to do that:

  // Avoid noise while switching:

  if (fd_video >= 0 && fd_audio >= 0) {
     CHECK(ioctl(fd_audio, AUDIO_SET_MUTE, true));
     CHECK(ioctl(fd_video, VIDEO_SET_BLANK, true));
     CHECK(ioctl(fd_video, VIDEO_CLEAR_BUFFER));
     CHECK(ioctl(fd_audio, AUDIO_CLEAR_BUFFER));
     }

but apparently that doesn't work - or I'm doing something wrong here.

We'll need a more elaborate CAM API for this - but I guess that's
on the driver developers' TODO list already...
