Switch掌机模式可以外接DAC再连耳机提高音质吗-Switch掌机模式可以外接DAC再连耳机提高音质介绍
问题是不是所有的DAC都能用在switch上，这位网友测试了四种dac，只有两种正常使用：
他发现问题所在：“Any DAC that is self-powered won’t work with the Switch.” 也就是说switch支持的是那种直接从usb口取电的dac(无需充电)。
另外由于各家dac的接头五花八门，可能需要另购type-c到相应接口的转接头或转接线才能让switch连接dac。
手头有dac的switch玩家不妨一试。
补充：
reddit上发现另一个测试DAC或USB声卡的贴子供大家参考：
测试兼容switch的型号：
-Asus xonar U3 (ASUS UA100 rumored to be C-Media based chipset)
-Behringer Xenyx 202 USB
-Cheap $5 Chinese USB soundcard
-JDS Labs C5D (Savvitech SA9027)
-Nuforce Cube (C-Media CM108AH)
-Nuforce Icon 2
-Schiit Fulla 2 (C-Media CM6631A in UAC1 mode)
-Schiit Modi 2 (C-Media CM6631A in UAC1 mode via switch set to 'S')
-Turtle Beach Audio Advantage Amigo II (C-Media CM102 based chipset)
-Turtle Beach Audio Advantage Micro (C-Media based chipset)
-UGreen USB 2.0 External Sound Adapter (C-Media HS-100B)
不兼容的：
-AudioEngine D3 (Texas Instrument TI1020B)
-AudioQuest Original DragonFly
-Centrance DACPort Classic (Texas Instrument TAS1020B)
-Centrance DACPort HD (XMOS U8)
-ESI Dr. DAC Nano (Tenor TE7022L)
-Fiio 'Andes' E07K (Texas Instrument PCM2706)
-Focusrite Scarlett 2i2 (Seems to be a Focusrite USB receiver chip)
-HifiMe UH1 (Savitech SA9227)
-Questyle QP1R
-Rotel RA-1570 (C-Media based chipset)
-Schiit Modi 2 Uber (C-Media CM6631A in UAC2 mode)
-Teac HA-P5 (Teac based USB chipset)
I think I'm seeing a pattern of what is supported by the Switch. Most likely only C-Media based USB chipsets using UAC1 (There is a report that Savitech SA9027 works too).
Reddit网友认为规律是支持的dac或usb声卡大都使用了C-media USB receiver芯片。
