Patch

In gstaudiobasesrc.c when setting src caps in gst_audio_base_src_setcaps(), the
ringbuffer is released after parsing the caps which sets some fields inside
spec and by releasing the ringbuffer, these data are then lost. This does not
happen the first time setting the caps has the ringbuffer is considered has
already release but any other time, this will fail.
In the patch in attachment, I just moved releasing the ringbuffer before
parsing the caps to avoid such issue.
