那篇我有看過,但都是討論音質,好像沒有提到聲音從顯卡輸出時,是誰在處理?


顯示卡或者CPU吧

例如我的筆電就有兩個音效晶片

這個是 Intel HDMI
代碼:
00:03.0 Audio device: Intel Corporation Haswell-ULT HD Audio Controller (rev 0b)
	Subsystem: Acer Incorporated [ALI] Haswell-ULT HD Audio Controller
	Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx+
	Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx-
	Latency: 0, Cache Line Size: 64 bytes
	Interrupt: pin A routed to IRQ 49
	Region 0: Memory at b0610000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: <access denied>
	Kernel driver in use: snd_hda_intel
	Kernel modules: snd_hda_intel



這個是 ALC 283
代碼:
00:1b.0 Audio device: Intel Corporation 8 Series HD Audio Controller (rev 04)

	Latency: 0, Cache Line Size: 64 bytes
	Interrupt: pin A routed to IRQ 48
