Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_203_292 ( id number, "payload type (pt)" text, "name" text, "type" text, "no. of channels" text, "clock rate (hz)" text, "frame size (ms)" text, "default packet size (ms)" text, "description" text, "references" text )

### Question ###
other than audio , what type of payload types are there ?

### Accurate SQL ###

SELECT "type" FROM table_203_292 WHERE "type" <> 'audio'
