96000 is the only thing that seems to work with my laptop and interface. Anything lower has a lot of issues with the audio and crashes the driver, unless I raise the buffer substantially. 96000 at 128 seems to be the sweet spot, except when it comes to area 33. This is a separate question but is what I just said a normal thing to happen. I thought a lower sample rate would allow for a lower buffer. That doesn’t seem to be the case with my laptop though.

I’m using an hp envy 17t cr-0000 with an intel i7 1260P processor. I have 32 gb of ram with a 1TB internal ssd drive and a 2tb external ssd drive holding Superior Drummer 3. My interface is a Universal Audio Apollo Solo with a Thunderbolt 3 connection. I’ve tried a couple different cables to make sure that’s not the issue. I’m triggering Superior Drummer 3 with my Roland TD-27 Module and my v-drum kit.
While using superior drummer 3, I turn on game mode and airplane mode. My drivers for my interface should be up to date and I believe I am using the correct one. I run Superior Drummer 3 through Ableton Lite.
Long story short, I’ve actually had this issue with two computers, brand new, the same exact model…. That’s a long story and holds no bearing to the issue.  That being the case, I don’t believe it’s a hardware issue though.
When I lower the sample rate I get crackling in the audio, until I raise the buffer to a higher rate. At that point the latency is quite noticeable. 96k at a 128 buffer seem to be the sweet spot. I get about 3.8 milliseconds of latency and no crackling, except when I’m using the presets in Area 33. I can raise the buffer rate but in return the latency.
Do you have any recommendations? Thank you for your help and time!

Hello, thanks for your help.  Game mode turns off windows update, and other background activity while you’re using whatever application you choose.  Airplane mode turns off all wireless connectivity to the device so I think I have those bases covered. I’ve turned off every application on start up that didn’t seem necessary.

I may not have explained things clearly.

The following examples are given using area 33 SDX with the Agrimotor preset. This one seems to have a few plugins running in it. Hence the performance issues.

At a 44100 sample rate with a 128 buffer I get 8.5 milliseconds latency. Any buffer lower then that cause Cracking and signals a cpu overload in Ableton.

At a 4800 sample rate and 128 buffer I get 7.3ms latency. Any buffer rate below that I get the aforementioned crackling and cpu overload signal.

At a 96000 sample rate I need to increase the buffer to 256. In order to avoid the crackling and cpu overload. At this I get about 6.5ms of latency.

Using these setting I’m seeing about 30% cpu usage in idle. Does all of this seem normal to you?

Generally, I have been using a 9600 sample rate at a 128 buffer. This gives me  3.8 ms latency. Which is the lowest I’ve been able to get it to work stability. I don’t have any real issue using this. Although the cpu is at about 50% at idle.

It seems like the computer can’t handle lower than a 128 buffer at any sample rate without having audio issues.

Does that sound normal given the components of my laptop or do you still believe there is something else going on? I can understand that the extra plugins running on this preset can cause cpu issues. Raising the buffer seems to solve the issue. Although it increases latency. If there is something else I can do to get a lower sample rate to work without issue with a lower buffer. I’d love to try it if it improves latency. As you can see from  my explanation. 9600 seems to give me the best results. I have no idea why
