           Summary: Web Audio context sample rate does not update
           Product: WebKit
           Version: 528+ (Nightly build)
          Platform: Macintosh
        OS/Version: Mac OS X 10.8
            Status: UNCONFIRMED
          Severity: Major
          Priority: P2
         Component: Web Audio
        AssignedTo: webkit-unassigned at lists.webkit.org

When switching between multiple audio devices with different sample rates, the sampleRate property of the AudioContext does not update to reflect the change.  In Chrome, the only way to get it to update, is to close the tab and reopen it.  Even if you create an entirely new AudioContext, the sampleRate remains whatever it was when the tab was first opened.  In Safari, the sampleRate updates if you create a new AudioContext in the same tab, but the original context does not update.

Expected behavior would be for the sampleRate property on each AudioContext to update appropriately when the output device changed.  I assume that the number of channels would also update appropriately.

I have not tested this on platforms other than Mac OS X, so reports as to the behavior there would be appreciated.
Thanks!
