[Ratheesh Kannoth] Yes.

[Ratheesh Kannoth] it was a bug. 
 
> Starting from NIX_SND_STATUS_CRC_ERR which was 0x09 and now it's 0x10.
[Ratheesh Kannoth] Yes. It should be 0x10 .  The real issue is - >enum was not in sequence.  (Eg ,,after 0x9 it should be 0xa).  But 
"static char *nix_snd_status_e_str" was assigned sequential strings.
