Hi John ,
I had this issue, but I haven't solved it yet. My current adhoc solution is to manually increment the gain when switching from Vpio. I contacted apple support about it but the conclusion was to ask me to file a bug report, which I haven't gotten round to doing.
Do let us know if you find anything. Thanks.
Pier.
