No, When the freeze happens I don't get any message just the freeze...The sound keeps going,as if the sim doesn't notice the freeze ( Strage)? Then when the needle hits 80 KTS the ding comes...Waiting a little longer another one comes,like if correspponding to the gear-up sound?...Then I close it via CRTL+Alt+Del then I notice that down on the task bar there a window dsd_fsx_xml_sound.gau. when I unstall the gauge,ie delete it from everywhere,put in my unedited .cfgs Try to fly I don't freeze...
I added your lines to the [VCockpit01] At the bottom,renumbered them to my next number in sequence...Didn't help?

ie:
...gauge46=CALLOUT_SmallJets!CALLOUTMIN,     0,0,0,0
gauge47=CALLOUT_SmallJets!CALLOUTAPPMIN,  0,0,0,0
gauge48=Captain_Sim.p727.sound!main, 0,0, 10,10, Captain_Sim\727\sound.ini
gauge49=dsd_fsx_xml_sound!Sound,2,2,2,2,\panel\v-one\v-one_Sound.ini
gauge50=dsd_fsx_xml_sound!Debugger, 420,550,600,80
