And I am apparently misinterpreting the PA claim "Good low latency behaviour" -- but I guess that this depending on the definition of low latency... Dedicated box means that this PC is a prototype for some real-world HW DSP device which the software will later be moved to. Working on a linux application clearly helps development, debugging and observability. Perhaps it's best to approach ALSA directly for the lowest latency. Have I understood it correctly that PA emulates ALSA, so I need to disable PA for that particular sound device before I can access it directly? OOI: What use has the synchronize stream argument in stream playback? Best regards, Svein
