 Hi,

 currently dvdringbuffer::safe_read only scans for new audio streams when
 either a new audio stream was selected that is different from the one
 currently playing  (case DVDNAV_AUDIO_STREAM_CHANGE) or when the video
 title set has changed (case DVDNAV_VTS_CHANGE).
 On one of my DVDs it so happens that both the menu and the first title
 being played have the same logical stream and VTS number which is why the
 audio streams are not scanned after transitioning from the menu and I get
 not sound (instead lots of "AFD Warning: Audio xxx ms behind video but
 already yyy video frames queued. AV-Sync might be broken." entries in my
 log).
 I added a check for a domain change to the {{{DVDNAV_VTS_CHANGE}}} case to
 trigger the audio stream scan and now the DVD is playing fine. I have not
 experienced any problems with other DVDs and do not expect any even if the
 audio streams are scanned too often now, remembering how often they used
 to be scanned with 0.23...

 Thanks and best wishes,

 Martin.
