Description

|
-----------
|
|
|
|
This ioctl is for Digital TV devices only. To control a V4L2 decoder use the

|
|
``V4L2_DEC_CMD_START_MUTE_AUDIO`` flag instead.
|
|
|

This ioctl call asks the audio device to mute the stream that is
|
|
currently being played.
|
|
|
|
Return Value

|
|
On success 0 is returned, on error -1 and the ``errno`` variable is set
|
|
appropriately. The generic error codes are described at the
|
|
:ref:`Generic Error Codes <gen-errors>` chapter.
