Bradley,
I have published the update to your device. Let me know if you do not get it. Please test the sound on device after the update as well and see if this helps at all. We ran into this issue early on in the creation of the touchscreen and it was resolved in a firmware release way back. I am not sure why this device is experiencing it and ours test units are not. I will keep the engineering team digging into this.
Thanks again,
Mike
