Re: [RDD] New audio imported in RD server, old audio plays out of RD Client

[Brad Beahm]

I've got some more info on this problem.  As it's still happening
sporadically even after some more 'padding' events between segments.

Today I managed to screenshot two cuts in separate carts where the audio
played wrong even though it looks like the server had imported the audio
correctly.  I'm wondering if the cut end markers can't be a clue.

Here are the screenshots: (linked because I'm not sure the list allows
attachments)

Screenshot 1 shows the Cut end marker occurring before the end of the
audio. The waveform appears to be correct, but yesterday's audio played
from the client.
Screenshot 2 shows the cut end marker occurring long after the end of the
audio. Again the waveform appears to be correct but the wrong audio played
from the client.

I have a log running on the dropbox that is used to import these files.
Here's what it shows for today:

  This is also my experience.

  We're running v2.10.3 from the Tryphon repositories at present.  Two
glitches happen frequently:  the time interval to post often
indicates :00 below the currently playing cart--even when there is
definitely a positive value for that cart.  When the cart advances to
'now playing', it always properly displays the time interval to post,
but this does not help live jocks who need to know that time before it
starts playing.

  Secondly, at the end of songs, the pie timer frequently shows the time
to end of the cart--even though it is set in the configuration to show
the time to segue.  When it gets to the segue, the pie countdown will
cut off with 2 to 3 seconds still remaining before it was supposed to
run out, and begins showing times for the new cart which was just
started.  This happens often.

Re: [RDD] New audio imported in RD server, old audio plays out of RD Client

[Brad Beahm]

I think a big component of my problem may be with this.
"but I believe that any file appearing next to a green START button in
rdairplay is an open file"
It's very possible the show segment that is playing the incorrect day's
audio is loaded in one of the lower positions of the rdairplay window by
the time the new audio comes from the syndication.

I don't think I'd be having a problem with my /var/snd mount because all
other audio is playing correctly.  The hard drive on the client machine is
nowhere near big enough to hold a copy of the server's /var/snd.

I'll try to 'pad some time' in between segments so there are more elements
(liners, songs, bumps) that will play in rdairplay before loading the next
segment into the green button play slots.

Thanks for the idea of a file being 'open' if it's in a play slot.
Brad

Re: [RDD] New audio imported in RD server, old audio plays out of RD Client

[Lorne Tyndale]

Have a look and see if your import has finished before rdairplay starts
to play the file.  I've run into something similar.  If I'm downloading
a file via FTP and importing it, and the file starts playing before the
import is finished - it'll play the "old" audio (since the new audio
isn't there yet).  As the import finishes the audio / markers / etc - is
all updated in rdlibrary, so the next time the audio plays you'll get
the new audio.

It could be something along these lines.
