Output device not loaded from session file

[MikaelStrom]

If I select my UM2 device for audio output in CubicSDR, it works fine. However, if I store the session, restart CubicSDR and load the session file, CubicSDR fails to restore the selected audio device (i.e. UM2 in my case) and falls back to the default ("Apple Inc.: Built-in Output"). The saved session file appears to be correct

            <bandwidth>6000</bandwidth>
            <frequency>118100000</frequency>
            <type>AM</type>
            <user_label></user_label>
            <squelch_level>-16</squelch_level>
            <squelch_enabled>1</squelch_enabled>
            <output_device>Burr-Brown from TI              : USB Audio CODEC </output_device>
            <gain>0.5</gain>
            <muted>0</muted>
            <active>1</active>

I see the same behaviour in 0.2.4, 0.2.5 and 0.2.6a
