Have you developed custom code to only allow audio response only and not video?

Hi,

Qualtrics.SurveyEngine.addOnload(function () {
    var questionId = this.questionId;

    function hideVideoButton(scope) {
        var btn = (scope || document).querySelector(".record-button.record-video");
        if (btn) {
            btn.style.display = 'none';
            console.log("Hidden .record-button.record-video", btn);
            return true;
        }
        return false;
    }

    // Classic layout: hide once on load, no observer needed
    var btnClassic = document.querySelector("#" + questionId + " .video-recorder-device-button");
    if (btnClassic) {
        console.log("Layout: Classic — hiding", btnClassic);
        btnClassic.style.display = 'none';
        return;
    }

    // New survey taking experience: target div.video-container
    var section = document.getElementById("question-" + questionId);
    if (!section) {
        console.warn("Section not found for:", questionId);
        return;
    }

    // Initial hide on load
    hideButton(section);

    var videoContainer = section.querySelector(".video-container");
    if (!videoContainer) {
        console.warn("video-container not found for:", questionId);
        return;
    }

    var observer = new MutationObserver(function (mutations) {
        var hasAdditions = mutations.some(function (m) {
            return m.addedNodes.length > 0;
        });
        if (hasAdditions) {
            hideButton(section);
        }
    });

    observer.observe(videoContainer, {
        childList: true,
        subtree: true
    });

    console.log("Observer active on:", videoContainer);
    observeVideoContainer();

});

Thank you, Vincent!

Meh, I’m sorry… I somehow managed to post a mix of 2 scripts.

Here’s my correct version, with the disconnect on page submit.

Qualtrics.SurveyEngine.addOnload(function () {
    var q = this;
    var questionId = this.questionId;

    function hideVideoButton(scope) {
        var btn = (scope || document).querySelector(".record-button.record-video");
        if (btn) {
            btn.style.display = 'none';
            console.log("Hidden .record-button.record-video", btn);
            return true;
        }
        return false;
    }

    // Classic layout: hide once on load, no observer needed
    var btnClassic = document.querySelector("#" + questionId + " .video-recorder-device-button");
    if (btnClassic) {
        console.log("Layout: Classic — hiding", btnClassic);
        btnClassic.style.display = 'none';
        return;
    }

    // New survey taking experience: target div.video-container
    var section = document.getElementById("question-" + questionId);
    if (!section) {
        console.warn("Section not found for:", questionId);
        return;
    }

    // Initial hide on load
    hideVideoButton(section);

    var videoContainer = section.querySelector(".video-container");
    if (!videoContainer) {
        console.warn("video-container not found for:", questionId);
        return;
    }

    q.observer = new MutationObserver(function (mutations) {
        var hasAdditions = mutations.some(function (m) {
            return m.addedNodes.length > 0;
        });
        if (hasAdditions) {
            hideVideoButton(section);
        }
    });

    q.observer.observe(videoContainer, {
        childList: true,
        subtree: true
    });

    console.log("Observer active on:", videoContainer);
});

Qualtrics.SurveyEngine.addOnPageSubmit(function () {
    if (this.observer) {
        this.observer.disconnect();
        console.log("Observer disconnected on page submit.");
    } else {
        console.log("No observer to disconnect.");
    }
});
