Fixed by Riot in Beta client, hopefully next patch will contain this fix!
It appears the fix for this is part of a rewrite of the entire audio system in LoL. It's still in development, and is occasionally added to the beta client for a short time for testing, but won't be pushed to the live client for a while.
