Fix Version/s: None
Ros 0.4.5RC2 with AC97 sound working in the current session
Scratch 1.4 from rapps
in sounds tab of Scratch, click "record a new sound"
Not with 100%, but reproducable with about 50% possibility
you will get an unhandled exception thrown by wdmaud.drv crashing the application.
Unfortunately l2l did not resolve the adresses for me, but it was official 0.4.5RC2 iso (maybe you can)
