Hi Ofer,

Thanks for reporting this bug to us. I would assume It’s a weird Flex SDK bug. We would be fixing this issue in the next SDK Drop.

So for the fix,

Modify line 174-176 from

<mx:RadioButtonGroup id="radioGroup" />
<mx:RadioButton id="nellymoser" group="{radioGroup}" selected="false"  label="{SoundCodec.NELLYMOSER}" click="changeCodec(event)" />
<mx:RadioButton id="speex" group="{radioGroup}" selected="true"  label="{SoundCodec.SPEEX}" click="changeCodec(event)"  />

To

<mx:RadioButtonGroup id="radioGroup1" />
<mx:RadioButton id="nellymoser" group="{radioGroup1}" selected="false"  label="{SoundCodec.NELLYMOSER}" click="changeCodec(event)" />
<mx:RadioButton id="speex" group="{radioGroup1}" selected="true"  label="{SoundCodec.SPEEX}" click="changeCodec(event)"  />

As you see changing the id of the RadioGroup we were using fixes this issue.

Thanks

Arun
