Pixel Streaming, EC2 and Sound Card

Hi everybody,

i’ve an UE4 application on EC2 / Server with GPU, etc. … Pixel Streaming ok.
But the sound is not stream if i quit my remote connexion.
So, i’ve installed Virtual Audio Cable… and ok… no sound via RDP when i connect - but sound via Pixel Streaming… good.
But if i quit rdp again… no sound in Pixel Streaming.
it’s like the deconnection modify the sound card… but i’ve parameter the RDP for not reading sound or using distant sound (not emulate)
Don’t know how to…
Have you got ideas ?
