Type

EXS API and SwitchKit API message

Description

Play File Modify 0x011C

NOTE: This message applies to the DSP Series 2 card only.

Use this message to modify a current play file session. You can modify the gain and speed of the playback, pause or resume the playback, or skip forward or backward (in 100 ms increments) through the current file.

When modifying a file that is playing to a conference, use the Conference AIB instead of the Channel AIB. If you are modifying a file that is playing to a conference, use the optional File ID TLV. If you use the File ID TLV, all instances of that File ID being played in the specified conference are modified. If the File ID TLV is absent, all the files playing into that conference are modified.
