+Subject: [PATCH] pcm_iec958: set channel status bits according to rate and
+ format
+
+This mimics snd_pcm_create_iec958_consumer in the kernel.
+
+The rate and wordlength bits will only be modified if they are
+set to "not indicated", which is now the default if no status
+option is used.
+
+This allows applications to override parameters determined from
+the stream or implement channel status bits extensions without
+needing to change pcm_iec958 code.
