Finally I was able to get in touch with an Xperia X and working on fixing Sailfish X issues.

So far so good, I was able identify the root cause: in-game audio. To be honest, I'm a little bit lost there - so, I would like to ask for help from the community...

Details below: there were many QML Audio components in use during the game: - one pool for weapon effects (5 QML Audio items) - one pool for four different audio effect for smashing monsters by hand (4 QML Audio element) - one dedicated one for game effect played when one life is lost

• if audio disabled, game just runs fine
• if I comment out all but the first pool of Audio elements game runs fine
• if first pool is enabled, together with one-and-single one from second pool (rest is commented out) games runs fine for a while, in-game effects are OK but after a while no sound any more - and app hangs-up in the game result page

QML Audio has been changed to Media Player, same effect - only achievement that I was able to see following log entry (after exporting QT_LOGGING_RULES="*.debug=true" ):

Feb 13 22:32:16 Sailfish kernel: afe_callback: cmd = 0x100ef returned error = 0x2
Feb 13 22:32:16 Sailfish kernel: afe_apr_send_pkt: DSP returned error[ADSP_EBADPARAM]

Feb 13 22:32:20 Sailfish sion[13927]: [W] unknown:0 - appsrc: push buffer wrong state

Last line could be from GSteramer code:

void QGstAppSrc::pushDataToAppSrc()
{
    if (!isStreamValid() || !m_setup)
        return;

    if (m_dataRequested && !m_enoughData) {
        qint64 size;
        if (m_dataRequestSize == (unsigned int)-1)
            size = qMin(m_stream->bytesAvailable(), queueSize());
        else
            size = qMin(m_stream->bytesAvailable(), (qint64)m_dataRequestSize);
        void *data = g_malloc(size);
        GstBuffer* buffer = gst_app_buffer_new(data, size, g_free, data);
        buffer->offset = m_stream->pos();
        qint64 bytesRead = m_stream->read((char*)GST_BUFFER_DATA(buffer), size);
        buffer->offset_end =  buffer->offset + bytesRead - 1;

        if (bytesRead > 0) {
            m_dataRequested = false;
            m_enoughData = false;
            GstFlowReturn ret = gst_app_src_push_buffer (GST_APP_SRC (element()), buffer);
            if (ret == GST_FLOW_ERROR) {
                qWarning()<<"appsrc: push buffer error";
            } else if (ret == GST_FLOW_WRONG_STATE) {
                qWarning()<<"appsrc: push buffer wrong state";
            } else if (ret == GST_FLOW_RESEND) {
                qWarning()<<"appsrc: push buffer resend";
            }
        }

        // After reading we might be all done
        if (m_stream->atEnd())
            sendEOS();
    } else if (m_stream->atEnd()) {
        sendEOS();
    }
}

V1.7-1 is out and it seems no crash/hangs-up so far during my testing with SailfishX. Please, try it by yourself to see whether issues have gone or not all...

The sad thing is, it is still a temporary release, where I have to disable all - :( - in-game sounds because it seems that caused the isses. Root cause is either an issue in SailfishX Qt multimedia module or I misuse it somehow. I thend to drop the latter one since original solution works 'everywhere' but SailfishX - and even more suspicious, Android version works just fine on SailfishX, too...

@Jk: if you happen to have time to test it, that would be great... ;)

There is v1.2 released and one suspicious feature is [temporarily] disabled: 'get extra coin' at the end of each game played. Please, try it out on SailfisX whether issue is still persistent - if so, this is random or happens end of every end, still...

I'm getting more-and-more confident that it is some Qt/QML issue related to NumberAnimation on QML Item property. The strange thing is it is non-existent anywhere else on other platforms/OSs... :(

Hard to get more sophisticated fix without actual SailfisX device but we are working on it with Jolla - but that takes some time...

quite disappointig results so far - sub 200 installs, not a single donation, not even a supporting email sent from the app - not so motivating, telling the truth...

are there so few sailors left? :(

v1.3 is released. All suspicious, eye-candy features (animated stars) are disabled at game end page until I get access to real device enabling figuring out what is the real cause...

please, try it out on Sailfish device and give feedback.
