I am working on an application that plays PCM audio over the DVB card. My first question is: Does the DVB card support mono playback? For Stereo I set the "channels" field of the LPCM header to "1". Trying other values here doesn't seem to set the decoder to mono. This isn't a major problem (I can always duplicate the data before sending it to the card), but it would be nice to have a definitive answer.
My second problem concerns initialising the card for PCM audio playback. I am creating a PES stream and writing it to /dev/ost/audio, but this only works with a newly loaded driver. On running my program for a second time, I just get silence. What is the correct sequence of commands to initialise a card in an unknown state for playing back of PCM audio? Do I just need access to the /dev/ost/audio device, or do I need to open and send commands to other devices? Is this possibly a bug in my PES stream?.
