Hey Wayne,

The schematics look good assuming that the GND_SENSE ground is shared with the codec.
If you haven't already there are also a good handful of FAQ's on the audio switches as well that would be a good thing to look over.

[FAQ] How do I Design with TI's Autonomous Audio Accessory Detection & Configuration Switch IC's (TS3A225E, TS3A226AE, and TS3A227E)

[FAQ] How do the Autonomous Audio Accessory Detection & Configuration Switch IC's from TI (TS3A225E, TS3A226AE, and TS3A227E) Detect Audio Accessory Type?

Thanks,
Rami
