SoundCard Input State

[BaptiAllain]

Hi HARP community,

I am trying to trigger sounds by sending digital signal to the input ports of the sound card. I have a "SoundCard Timestamped InputState" after the "SoundCard" node but for some reasons, I see only the timestamps associated with DI0. I am able to see that the digital signals are well sent to DI1 with an oscilloscope, but it is like the sound card was not able to receive them.
In the same line, in the SoundCard InputState Payload, it is possible only to configure IN0 while in the SoundCard OutputState Payload, it is possible to configure it to have the sate of all input ports.
Does it mean it is not possible yet to trigger sounds from digital inputs 1 and 2?

Thank you in advance for your help!
