Hi. Thanks for the answers. I tried several USB sound cards. If I don’t share it, it doesn’t stop, it works continuously on the RPi. When I share it, it works fine for a while and appears as a normal audio device on the client side. By monitoring the device, I can hear the sound from the remote audio input (analog audio line input). When it stops after a while, apparently nothing changes. NoMachine also indicates that it is shared on the RPi. On the client side, it is also there in the device manager and audio devices, but only apparently, in which case the client side device manager and sound settings basically freeze, and in this case nothing can be set. In this case, you either need to restart the Windows computer on the client side or turn off the share and re-share and it will work again. I may not be able to solve this. Regardless, congratulations on the software and the added support. I might buy the software later.
