Release for gen3-test v3

Alsa: fix throwing empty exception

Calling throw without active exception leads to crash because according to throw
definition: "This form is only allowed when an exception is presently being
handled (it calls std::terminate if used otherwise)".
The fix is to return Alsa::Exception instead.
