+Summary: alsasink fails to negotiate with audio decoders
+
+I recently upgraded to GStreamer 0.7.3, and at the same time finally got
+around to switching my default audio sink from osssink (using ALSA's
+emulation os OSS) to alsasink, but it didn't work. When trying to use
+alsasink for audio output it cannot negotaite with whichever audio decoder
+is used.
+
+As an  example, if I run "filesrc location=/path/to/music.ogg ! vorbisfile
+! alsasink" it fails, reporting "ERROR: /pipeline0/vorbisfile0: negotiation
+failed on pad vorbisfile0:src". The same error occurs if I try to play a
+mp3  with mad as the decoder. However some other audio sources seem to
+work, such as "sinesrc ! alsasink".
+
+I haven't had a chance to do anything much with GStreamer yet, but from
+what I know of the basics it is probably a problem with the sink
+negotiating the data stream it wants. If anyone wants I can attach the
+output of gst-inspect for alsasink and osssink, or run more test with
+various pipelines to try to find what exactly is causing this.
