Ubuntu Linux Running Two Instances of Player

At first I thought it was a fluke or my imagination at best. I have audio in my presentation and I thought there was a slight reverberation or echo. Sometimes it would be more prominent than other times. On occasion it would be quite distinct: The audio would be playing twice about 1 second apart. Very disconcerting, even for jazz. (That's a little joke.)

I've checked my presentations for any duplicate audio tags and found none.

My display is on Ubuntu 14.04 LTS and I was listening to the presentation while working. It played for a good 3 hours, still sounding a bit like an echo, but not distracting, when it suddenly started to sputter on the stream. The audio stopped then skipped back a second or so several times before finally stopping altogether. I went into my Rise Vision console and restarted the player. The box took a couple of tries before the player started and when it finally came back, the 1 second lag was there again. It is like there are two instances of the player playing.

What do I look for in Ubuntu to see where the player is being run twice?

Hey Adam!

I really doubt that this is a case of multiple instances of Rise Player running. You would be getting a duplicate display error if that were the case.

Instead, I think it has to do with the configuration of your presentation. I notice that you have 3 HTML widgets in the presentation, all with an <audio> tag. Could you try removing the audio tags from two of the 3, and leave it in the third? Save and publish your presentation, and see if that resolves the issue.

Let me know!

Yes, this was the issue. I had forgotten that I was playing around with adding the audio tag to my Google Slide presentation. On top of that, I duplicated the item in the playlist, thus creating multiple instances. Thank you for your help.

Glad I could help, Adam! You've got a neat presentation. I had my headphones in and was a little frightened when the jazz started playing out of nowhere :)

Thanks, Blake! For what it's worth, the display is broadcast to a school channel on the local cable network. We don't have a lot of content, so I found the public domain stream to try to keep people at least tuned in, if not watching. :D

What you can also try is to move the code in the HTML widgets into a separate .html page and then upload that on to Rise Storage or your own web server. Then you can use the Web Page Widget to link to the individually built .html pages, making sure to select the 'Unload Web Page' option in the Widget settings. That way, when the presentation is showing one of the Widgets, it is not playing the audio tag from the other Widgets linking to the html page.

Let me know if you have questions with the above.

Thank you for the recommendation. I just went ahead and put an invisible placeholder in my presentation with an HTML widget as the only one. HTML widget with my audio tag does the trick so far...
