non MSD direct output, by releasing the MSD patch before the request
if it is using the same output device. The MSD patch is recreated
all direct outputs have been closed.

Test: atest CtsMediaTestCases:AudioTrackSurroundTest#testPlayIEC61937_48000
      on an Android TV device with HDMI output active and an MSD that does
      not support IEC61937
