Zusammenfassung:The invention discloses a low-delay audio distribution method based on a network card, a module and a device thereof, and the method comprises the following steps: S1, obtaining an audio distribution instruction sent by a main control module, and requesting audio data from the main control module; S2, acquiring audio data sent by the main control module, and storing the audio data in a cache memory; S3, acquiring timing information of a timer, and regularly sending audio data to the target equipment; and S4, judging whether the cache amount in the cache memory is lower than a preset value or not, if so, executing S1, and if not, executing S3. In the invention, through precise timing of the timer, the device can accurately send the audio data to the target equipment in real time, and a stable playing effect is brought to system audio distribution. 本发明公开了一种基于网卡的低延时音频分发方法、模块和装置,所述方法包括以下步骤:S1:获取主控模块发送的分发音频指令,并向主控模块请求音频数据;S2:获取主控模块发送的音频数据,保存至缓存储存器中;S3:获取计时器的计时信息,定时向目标设备发送音频数据;S4:判断缓存储存器中的缓存量是否低于预设值,若是,则执行S1,若否,则执行
