Please try this new patch - I get audio again here! I've also added in code to output the status of the encoder if something goes wrong in future.
Great work. I have sound too. Thank you very much.

found that it would frequently lose audio sync, or acquire strange buzzing noises. Oh, and my test decoder program (kaffeine, based on xine) tended to lock up when the video went missing as well - so the encoder must have been outputting rubbish.
It's really annoying: the SAA6752hs encoder chip has all these funky commands like "START", "STOP", "PAUSE" etc - problem is they don't work properly!
To fix that, if you unplug the video it will now hard reset the encoder. When you plug it back, it will reconfigure and restart it with the last settings used. It means you won't get any data at all if the video signal is missing, but theres no other way to be 100% reliable with this chip.
Do you have some documentation from the saa6752hs-encoder?
I'm looking for information about usefull parameters (picture format, bitrates, etc)
