What's the debug message detail on that? (not-negotiated?)

That depends on the exact error, but if it's not-negotiated it's likely
got something to do with caps.

That depends on what you're pushing into appsrc. If it's raw PCM audio,
it should be in chunks of bytes_per_sample * channels.

audio_caps = gst_caps_new_simple("audio/x-raw-int",
"width", G_TYPE_INT, (gint)16,
"depth", G_TYPE_INT, (gint)16,
"channels" ,G_TYPE_INT, (gint)2,
--> "signed",G_TYPE_INT,1, <--
"rate", G_TYPE_INT, 44100,
"endianness", G_TYPE_INT, (gint)1234,
NULL);
The signed field should be of G_TYPE_BOOLEAN.
