AUDIO TESTS VIA VIRTUAL AUDIO DEVICE

Create audio sinkhole and subdevices

Note: This command needs to be run again after every reboot

sudo modprobe snd-aloop index=1,2 enable=1,1 pcm_substreams=1,1 id=CHAT1,CHAT2

check if devices have been created

aplay -l

Output should be like this:

    Karte 0: Intel [HDA Intel], Gerät 0: Generic Analog [Generic Analog]
      Sub-Geräte: 1/1
      Sub-Gerät #0: subdevice #0
    Karte 1: CHAT1 [Loopback], Gerät 0: Loopback PCM [Loopback PCM]
      Sub-Geräte: 1/1
      Sub-Gerät #0: subdevice #0
    Karte 1: CHAT1 [Loopback], Gerät 1: Loopback PCM [Loopback PCM]
      Sub-Geräte: 1/1
      Sub-Gerät #0: subdevice #0
    Karte 2: CHAT2 [Loopback], Gerät 0: Loopback PCM [Loopback PCM]
      Sub-Geräte: 1/1
      Sub-Gerät #0: subdevice #0
    Karte 2: CHAT2 [Loopback], Gerät 1: Loopback PCM [Loopback PCM]
      Sub-Geräte: 1/1
      Sub-Gerät #0: subdevice #0

Run tests:

Terminal 1: Ping

python3 PING.py --txmode 12 --rxmode 14 --audioinput 2 --audiooutput 2 --frames 1 --bursts 2

Output

BURSTS: 2 FRAMES: 1
-----------------------------------------------------------------
TX | PING | BURST [1/2] FRAME [1/1]
RX | PONG | BURST [1/2] FRAME [1/1]
-----------------------------------------------------------------
TX | PING | BURST [2/2] FRAME [1/1]
RX | PONG | BURST [2/2] FRAME [1/1]

Terminal 2: Pong

python3 PONG.py --txmode 14 --rxmode 12 --audioinput 2 --audiooutput 2

Output

RX | BURST [1/2] FRAME [1/1] >>> SENDING PONG
RX | BURST [2/2] FRAME [1/1] >>> SENDING PONG
