[linux-dvb] Audio replay: driver bug or done something wrong?

[huels@iname.com (Stefan Huelswitt)]

Hi,

I'm want to have the following setup: while watching a live
program, I want to disable live audio, replay some audio from
memory and then switch back to live audio.

To switch from live audio to audio replay I use (this is from
inside vdr):

  CHECK(ioctl(audioDev, AUDIO_SELECT_SOURCE, AUDIO_SOURCE_MEMORY));
  CHECK(ioctl(audioDev, AUDIO_SET_AV_SYNC, false));
  CHECK(ioctl(audioDev, AUDIO_PLAY));

Now I can replay audio from memory fine. To switch back to live
audio I use:

  CHECK(ioctl(audioDev, AUDIO_STOP, true));
  CHECK(ioctl(audioDev, AUDIO_CLEAR_BUFFER));
  CHECK(ioctl(audioDev, AUDIO_SET_AV_SYNC, true));
  CHECK(ioctl(audioDev, AUDIO_SELECT_SOURCE, AUDIO_SOURCE_DEMUX));
  CHECK(ioctl(audioDev, AUDIO_PLAY));

Doing this, the video goes black for a second and then comes
back, but there is no audio.

Am I doing something wrong or is this a driver bug?

CU
