dalecurtis@, can you please look into it. Thanks.

Seems this device has broken float audio output; which is unfortunate since it's tested as part of the CTS verification for Android Lollipop+ devices. I'll add a blacklist for it for M60; unfortunately there's no workaround for users presently.

Disable float audio output on Vivo devices; they're broken.

Play Store users and TE verification report these devices play
garbled audio when using float. Disable for all Vivo devices since
they're still shipping 2017 models with Lollipop.

Don't have this device so will ask TE to verify on the next canary release with this patch and merge to M60 if successful.

This issue is fixed on latest M61-61.0.3144.0, but still observed on latest M60-60.0.3112.51

Great, thanks for testing. Marking as merge request for 60.

This bug requires manual review: M60 has already been promoted to the beta branch, so this requires manual review

Approved for M60 branch 3112.

Hmm Error: Command 'cl land --bypass-hooks' failed: Command '['git', 'cl', 'land', '--bypass-hooks']' returned non-zero exit status 1

Will try again.

Nevermind, seems to have worked now...
