Yes, we are dealing with very low latencies. Our embedded device is a pinball machine. Yes, the performance improvements in user-mode are measurably better just by looking at percentages in top. I can't even get playback in system-mode to be without static (i don't know what else to call it). In user-mode it sounds perfect. ‐‐‐‐‐‐‐ Original Message ‐‐‐‐‐‐‐ On Friday, July 24, 2020 9:27 AM, Arun Raghavan <arun@xxxxxxxxxxxxxxxx> wrote: > On Fri, 24 Jul 2020, at 8:29 AM, jtharkey wrote: > > > We're trying to get away from running PA in system mode on an embedded > > device because of performance.
