Hi, The 9.0 release notes mention memfd as a SHM transport variant that can make Pulseaudio perform better when running in the system mode, but the implementation seems to disallow it [1]. I'm wondering if there still are plans to make this work. Laurentiu [1] https://github.com/pulseaudio/pulseaudio/blob/master/src/pulsecore/protocol-native.c#L2646-L2680
