Microsoft recently pushed out a small firmware update to the Surface Pro 4, bringing improvements for the Realtek audio driver. Unfortunately, that's all that's included in the latest update, but it should help to improve all-around stability and Cortana performance, Microsoft says.

Surface Pro 4 picks up small firmware update

Here's a look at the lone update, from the Surface Pro 4 update tracker (via Neowin):

  • Realtek Semiconductor Corp. driver for Realtek High Definition Audio (SST) - v6.0.1.7895 - Improves system stability and Cortana performance.

This is the first firmware update that Microsoft has pushed to the Surface Pro 4 since the end of August, so it's good to see something come along. The update actually began rolling out on December 8, according to the tracker, so you should be able to find it in Windows Update now.
