Basic introduction
Realtek Realtek HD Audio official sound card driver section first LOGO
Realtek ALC861/ALC880/ALC882/ALC883/ALC885/ALC887/ALC888/ALC889/ALC890/ALC260/ALC262/ALC268/ALC272/ALC273/ALC662/ALC663/ALC665 HD Audio official sound card driver version R2.78 For Win7-64/Win8-64/Win8.1-64/Wi10-64 (released on May 22, 2015) Realtek is uncharacteristically uncharacteristic. It originally took nearly a year to release a general sound card driver. Now in just one month, 3 versions have been released. Today is the third version officially released by Realtek, version R2.78, which also supports Win10 system.

Judging from the official update instructions, it does not take two days. It is just a list as usual. However, I guess that the Realtek sound card driver recently supports the Win10 system. It may be to cooperate with Microsoft's push of the latest Windows 10 Build 10122, so for Win10 users, you may wish to update this version. Official driver, naturally stable.
