You said that you use a dedicated box for the processing, so using the
default sound server doesn't sound like a hard requirement. In that case
I recommend using JACK, it's designed for this kind of use cases.
Thanks
Too bad. Using PA is convenient, as it's already integrated into most
distros. 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,
