The New York Times stated that this was specifically asked the Pentagon, given the phrasing of their announcement and got a no-comment. It's certainly a good thought.

“This was a unique demonstration of the United States’ ability to target facilities that our adversaries seek to keep out of reach, no matter how deeply buried underground, hardened or fortified,” Mr. Austin said in a statement late Wednesday night. “The employment of U.S. Air Force B-2 Spirit long-range stealth bombers demonstrate U.S. global strike capabilities to take action against these targets when necessary, anytime, anywhere.”
Attacking so-called hardened buried sites generally requires the use of specially built bombs that have much thicker steel cases and contain a smaller amount of explosives than similarly sized general-purpose bombs. The heavy casings of such “bunker buster” bombs allows the munition to stay intact as it punches through soil, rock or concrete before detonating.
The B-2 is the only warplane that can carry the largest of this class of weapon in the Pentagon’s inventory: a 30,000-pound GPS-guided munition called the GBU-57 Massive Ordnance Penetrator, or MOP, that contains the equivalent of about 5,600 pounds of TNT. A Pentagon spokesman declined to say whether that weapon was used in the attack on Wednesday.
EDIT: Reading the above, maybe the situation is basically both of the two guesses here combined.
It's a message to Iran, and the reason that the B-2 specifically is involved in that message is because it can drop very large bunker-busters, which could presumably penetrate Iranian facilities.
I am not an audio professional and I personally am not in love with the interface in my limited use of the thing -- though my basis for comparison is only much-simpler software packages -- but I have consistently seen Ardour recommended as a DAW under Linux.
If you have not considered it, I'd probably at least have it on your list to look at.
