   Dear Meiyou,

Greetings, this is ASRock TSD.

To support audio 5.1 surrounded, it should use the HD audio front panel and enable the multi-channel audio feature through the audio driver.
The audio driver is supported for Windows 10. Therefore, we tested the function in Windows 10 OS.

With Linux OS, please install the suitable audio driver and please be noted that it is not native support.

Thanks!

All the best,
ASRock TSD
