Newbie questions: osxaudiosink, USB DAC and integer mode

[novazeta]

Ok so it turns out that I have to stick with gstreamer 0.10, as that is the
version that Mopidy supports. However, I have updated to the tip of the
0.10 branch. Is this the correct way to use capsfilter (using the shorthand
here)?

gst-launch-0.10 audiotestsrc ! audio/x-raw-int,width=16,depth=16 !
osxaudiosink

As a reminder, these are the capabilities of osxaudiosink in the version
that is at the tip of the 0.10 branch of gst-plugins-good:

    Capabilities:
      audio/x-raw-float
             endianness: { 1234 }
                 signed: { true }
                  width: 32
                  depth: 32
                   rate: [ 1, 2147483647 ]
               channels: [ 1, 9 ]
      audio/x-raw-int
             endianness: { 1234 }
                 signed: { true }
                  width: 32
                  depth: 32
                   rate: [ 1, 2147483647 ]
               channels: [ 1, 9 ]
      audio/x-raw-int
             endianness: { 1234 }
                 signed: { true }
                  width: 24
                  depth: 24
                   rate: [ 1, 2147483647 ]
               channels: [ 1, 9 ]
      audio/x-raw-int
             endianness: { 1234 }
                 signed: { true }
                  width: 16
                  depth: 16
                   rate: [ 1, 2147483647 ]
               channels: [ 1, 9 ]
      audio/x-raw-int
             endianness: { 1234 }
                 signed: { true }
                  width: 8
                  depth: 8
                   rate: [ 1, 2147483647 ]
               channels: [ 1, 2147483647 ]
      audio/x-ac3
                 framed: true
      audio/x-dts
                 framed: true
