Hi Star, Can you help to check audio path switching part?

I can duplicate it on the Nexus4 with latest SW. The root cause should be as the same as Bug 983539, please see the comment-14[1] of Bug 983539. But Bug 983539 is only resolved in 1.3T branch instead of master branch. And another bug (Bug 927862) is working on fixing the bug. So I mark as duplicate as it.
