Windows 10: No sound. Realtek entry is missing from Device Manager

I have Asus ROG Trix with Win 10 Pro 64-bit, version 1803.

Yesterday at shutdown, I had sound from various sources - for example, YouTube. Today I have no sound from any source.

When I looked in Device Manager, the entry for Realtek has disappeared. That entry was present approximately one week ago when I disabled and re-enabled the driver to cure no sound in YouTube.

Any advice?

Thanks.

Device Manager "other" entries


After a fresh W10 1703 fully updated install on a 3148 Inspiron laptop, four OTHER DEVICES appear in Device Manager: PCI Data Aqquisition and Signal Processing Controller and three 'unknown devices.' "Drivers not installed; no compatible driver can be found."

Prior to this install several Intel drivers were listed under Programs and Features. likely because they were added after the fact. They are not listed now and Intel's update utility reports nothing missing. SFC is good and PC operation is normal.

The errant entries are redetected at boot even if disabled, or uninstalled via Safe Mode. Suggestions on banishing them for good would be appreciated.
