 Issue 632627  has been merged into this issue.

This seems like a real race that needs fixing, it's hitting
DCHECK(HasOneRef()) << "Only the AudioManager should hold a reference";
in AudioOutputResampler::Shutdown() and seems to have been for a long time.

After disabling on ASan, this is still failing a lot on linux_chromium_chromeos_rel_ng and linux_chromium_chromeos_ozone_rel_ng. These failures also appear to be because of DCHECK(HasOneRef()) << "Only the AudioManager should hold a reference" in AudioOutputResampler::Shutdown.

tommi@?

I'm going to disable the test for now.

The last flake for this was built from r410622 + patch, which was just before I disabled the test (r410627), so disabling the test worked. Removing label again.

I'm not actually working on this, so tagging for re-triaging.

yiningc - can you see if there's someone else that can take a look? It's not going to really make a big difference to assign the bug back to me :)

stale bug.
