Hi,

I was testing recording voice with gstreamer. I used autoaudiosrc to set the
recording source. For all desktop platforms such as Linux, Windows and MacOX,
recording works fine. But for iOS, i'm getting broken voices and for android,
no voice at all. I have tried changing sample rates but no luck. Code is -

    audiosrc = gst_element_factory_make ("osxaudiosrc", NULL);
    g_assert (audiosrc);
    audioconv = gst_element_factory_make ("audioconvert", NULL);
    g_assert (audioconv);
    audiores = gst_element_factory_make ("audioresample", NULL);
    g_assert (audiores);
    /* the encoding and payloading */
    audioenc = gst_element_factory_make ("alawenc", NULL);
    g_assert (audioenc);
    audiopay = gst_element_factory_make ("rtppcmapay", NULL);
    g_assert (audiopay);

    gst_bin_add_many (GST_BIN (pipeline), audiosrc, audioconv, audiores,
                      audioenc, audiopay, NULL);

    if (!gst_element_link_many (audiosrc, audioconv, audiores, audioenc,
                                audiopay, NULL)) {
        g_error ("Failed to link audiosrc, audioconv, audioresample, "
                 "audio encoder and audio payloader");
    }

    GstCaps *rescaps;
    rescaps = gst_caps_new_simple("audio/x-raw", "format", G_TYPE_STRING,
"S32LE",//also tried "S16LE"
                                  "rate", G_TYPE_INT, 48000, //also tried
44100, 32000, 16000
                                  "channels", G_TYPE_INT, 2, //also tried 1
                                  NULL);
    gst_element_link_filtered (audiosrc, audioenc, rescaps);
    gst_element_link (audioenc, audiopay);

Please, help me with this bug.
