Reaper v 2.53 is constantly changing my HW buffer!
This happened with a much earlier build, but then went away with later builds.
The session I always work with runs fine with a 128-sample buffer, heck it just barely runs with a 64-sample buffer, and no clicks, but the cpu's peak at around 60-70% so I dial it back for safety.
With a 128 buffer, my cores never go above 35%.
Yet, EVERY time I re-launch, my buffer has been reset to 256. I have to manually put it back to 128, and then all is well.
It's doing this on both of my systems.
What gives? There is a HUGE difference to me in real-time latency, and it's hard to remember to set it every single time. Can this be fixed?
----------------
System Details:

Session sample rate: 44.1K
Control surfaces: Behringer B-control rotary & X-Session pro.

Does it happen with another project?

Yes, if I also power-cycle. Even with session that are using lower ram & less than 20% cpu.

it might be your audiocard drivers.
also, if i open protools, it totally messes with my latency settings as well.

Good thought.
I'll call Lynx on Monday.

ReaRoute may be involved.
No help from Lynx. They said that the HW buffer setting is 100% controlled by the DAW.
I think I found something-
1: This may be partially related to ram-allocation issues. It seems to happen more often in sessions that are pulling a lot of ram (over 1 gig)
2: It MAY have something to do with ReaRoute. Last year I had terrible problems with Rearoute causing distortion, and the HW buffer would constantly have to be tweaked, or would reset.
I'm not 100% sure, but I'm fairly certain that I'm only seeing this problem (now, after some am tweaks) with ReaRoute sessions.
Also, I just heard some similar distortion today, several different times. re-setting the buffer made it go away, just like in the bad old days with earlier ReaRoute versions.
