How do you restrict the number of times an audio clip is played?

I may have something cooked up, but a couple of questions first:

• Do you need folks to be able to pause the audio?


• Do you need folks to be able to control any other parts of the audio file in any way (e.g. scrubbing and/or volume control)?

AHammell Thank you so much! This was super helpful If I have another question where I would like the participant to only be able to listen to the audio clip once, is there a way to modify this code to do that?

AHammell Thanks so much! I put your suggested code into the javascript, but for some reason, the audio clip seems to play on a loop once the "play" button is pressed. Do you have any idea where I could have gone wrong?

AHammell I'm not quite sure how to embed my JavaScript into the discussion like you did, and for some reason Qualtrics is blocking my copy/paste of my code.
HMTL View:
9. Remember to listen carefully and make sure that your computer volume is on, as you will only be able to listen to the clip once. 

Hello AHammell! Thank you very much for this helpful information. I'm wondering how to adjust the script you've provided if each of my questions has TWO audio files in it. Moreover, my audio files are in multiple choice answers, so I'm not sure if there is a way to edit the HTML of those answer choices. Grateful for your assistance!

Hi AHammell! Thanks so much for providing all this coding!!! Unfortunately the HTML code is not working for me anymore. It used to work when I uploaded my audio files through the "rich content editor", but I don't seem to be able to do that anymore, and inserting an URL from a SoundCloud or Google drive audio file into the

Hi AHammell, thanks for your reply and apologies for getting back to you so late. In the end I've avoided the issue by using Qualtrics Media Library, so everything looks good on that front.
The codes you've kindly provided in this thread work fine. The only problem is that, although the 'Play' button disappears once the audio has been played the allowed amount of times (in my case, once), one can still re-play the audio by clicking on the empty area where the 'Play' button used to be. In other words, the button is hidden but that doesn't necessarily prevent people from playing the audio. Is this normal, or is it just an issue with the Preview mode?
Is there a way to make sure the playing function is fully disallowed/deactivated after an audio has been played a given amount of times?
Thanks for your help!

Hi AHammell, thanks so much for your reply, which I've just seen (clearly I must have missed the notification)!
I've added the new bit of coding but it doesn't seem to make any difference. The audio button disappears when it's supposed to, but this was already the case. The problem is that, even though the button is no longer there, you can still play the audio by clicking on the space where the button used to be.
Do you know if there is a way to work around this? Perhaps by deactivating controls/mouse movements after a given audio has been played a certain number of times?
I have no idea whether this is possible at all but I'm trying to think outside the box :-)
Thanks so much for your help!

Thanks so much! I've just tried both but unfortunately neither of them works. Let me know if you can think of anything else :-)

Sure! Thanks so much! :-)

Chiara_A Apologies for the late reply. I looked at your code in Qualtrics, and it is working appropriately for me. See here: https://umn.qualtrics.com/jfe/form/SV_1BJa96GMJRz3ghg
I've attached the QSF file for the linked project so that you can import it yourself and see how it is implemented in this survey.
TestAudio.qsfDo you have any other JavaScript that you're using in your survey that could be interfering?

https://community.qualtrics.com/XMcommunity/discussion/comment/47037#Comment_47037Thanks for the quick reply. I have implemented changed the HTML for each question and the labeling in the JavaScript for "audiofile#" and "audiobutton#" and everything is working perfectly.
It seems that I did not need to change the JS variables' names for it to work. I'll test this out and update the answer here in case I have to modify that as well.
Thanks again for the help AHammell!
