It seems to work here, in the latest git master.

Taking a quick look at 1.15.1's source, it does seem as though 
alSourcePlay is neglecting to set the source's NeedsUpdate flag, so it 
continues using the old parameters it had from before stopping until 
something else triggers an internal update.

The code in master does set the source's NeedsUpdate flag when starting, 
so it gets properly updated for any listener changes that may have 
happened while it was paused.
