When connected to the sound card separately, the two audio cables function as expected.
Connecting two audio cables simultaneously to the sound card (whether connected to a computer or not) can cause transmission to be triggered.
The model of my sound card is VAB-S13. I suspect that the internal circuitry of the sound card complies with the PTT (Push-to-Talk) definition, which leads to transmission.
