Soundblaster 個driver會有得set DTS / Dolby 咁佢自動將所有connect既野做surround
但好奇怪既係
插analog既 front rear 佢的確係 front rear
但optical out既Ray front rear center sub 佢包辦
結果有時有奇怪既唔同步
set左16bit instead of 24bit 好似好左
但佢完全無得config latency
Realtek onboard既直情無得咁玩
一係光纖 一係analog 無得一齊
BTW都打算入多隻Symfonlisk 咁就夠一pair rear
但要諗點樣打佢上牆
