如何在Raspberry Pi上使用C ++将收到的UDP音频数据正确写入ALSA

I have 2 Raspberry Pis and 1 of them transmits UDP frames of Audio data to the other Raspberry Pi. The UDP Packets received are 160 Bytes each. The transmitting Raspberry Pi is sending 8KHz 8-bit Mono samples. The receiving Raspberry Pi uses Qt 5.4.0 with QUDPSocket and tries to play the received data with ALSA. The code is below. Each time the "readyRead " signal is fired when bytes arrive on the receiving Raspberry Pi, the Buffer is written to ALSA. I have very Choppy and Glitchy sound coming out of the headphone Jack on the Receiving Pi - but it is recognizable. So it is working but sounds Terrible. I have 2 Raspberry Pis and 1 of them transmits
