Windows 10: Using my Surface Pro 7, audio format option is greyed out

The audio formats option on my surface pro 7 are greyed out and cannot be changed from 48kHz, 16 bit. I seem to remember changing them in the past. I have tried uninstalling the driver, downloading the latest surface firmware, but the problem persits. What audio formats does the surface pro 7 support by default?

Surface Pro 3 - No HDMI Audio Output

Hi, my Surface Pro 3 HDMI audio stopped working last week, after a year or more of use. Any ideas would be appreciated. I only use this PC to stream entertainment to the TV, and sometimes for Skype. No changes made by me. Thanks!

Here's what I've tried so far:

• Switched cables.
• Switched output devices (receiver and direct to TV)
• Reset Surface Pro
• Disabled/Enabled UEFI TPM in BIOS
• Disabled/Enabled "Intel Display Audio" in device manager
• Messed around with advanced audio settings and format

Surface Pro 3 - No HDMI Audio Output

I’ve solved this by buying an Active minidisplay port to HDMI. I get sound through HDMI now.
