市面上的电视接收卡,一般随卡附送一条两头皆为φ3.5mm插头的双声道音频线,一端插入电视卡的音频输出接口,另一端接声卡的音频输入接口。这种接法虽然操作简便,但存在明显缺陷:如果所用的声卡为板载集成的四(4.1)或六(5.1)声道声卡时,因为设计上音频输出、输入共用插口的原因,当系统以多声道放音(如玩游戏或播放DVD等)时,电视卡的音频线必然会占用其中的一个输出接口。除非把它拔出,另接入音频输出线,否则系统不能以正常的多声道放音。
The TV card on the market, usually with a card attached to both ends of φ3.5mm plug two-channel audio cable, one end of the TV card inserted into the audio output port, the other end of the audio card to the audio input. Although this connection is easy to operate, there is a clear flaw: if the sound card used is an onboard integrated four (4.1) or six (5.1) channel sound card, because of the design of the audio output, the reason for inputting the common socket is that when the system To multi-channel playback (such as playing games or playing DVD, etc.), the TV card’s audio cable will inevitably occupy one of the output interface. Unless it is unplugged, the other access to the audio output line, otherwise the system can not play with the normal multi-channel.
