XPS 15-9570, Windows 10, high DPC latency, acpi.sys

Come on Dell, we are waiting for the solution.

Just want to add my voice to the list of complaints. I have read just about every forum and web posting related to the XPS 15 9570's audio issues, and yes, it's all true. I mulled returning the DELL, but in the end I decided that for my primary use of the Dell, it would be ok, and I didn't want to give up other aspects that I liked about it.  Normal audio playback is usually ok, although I have had times where I randomly get noise (e.g. sometimes after resuming playback on a video after pausing it).  The issue that bugs me the most is audio latency for real-time playing of virtual instruments, which I do sometimes as a musician. The latency renders the Dell completely unusable for this purpose, at least using the onboard audio and ASIO4All. I have yet to try with an external audio interface, but from what I read that also may be an issue. If anyone has any experience using a Thunderbolt audio interface with the XPS 15, please let us know if the latency is ok with that. I have done audio playback, including virtual instrument MIDI playback with a DAW, and that was ok, but real-time playing is impossible.

Here's an update. I tried my XPS 15 9570 with a "proper" audio interface (the Presonus Audiobox USB). It's basic, but from a reputable company and with ASIO drivers written specifically for the device. I'm happy to report that I was able to get good latency performance for real-time playing of virtual instruments. I was able to lower the buffer to 128 samples on two different programs without getting pops & clicks.  The first time I lowered it to 128 I did get some clicks, but later I was able to get it without clicks. In any case, the latency at 256 samples was also acceptable.  I would still be curious as to latency performance with virtual instruments using a thunderbolt interface.

I guess I was freaking out earlier because in previous computers I have used (much more low-end than the XPS 15), I was able to get decent latency playing virtual instruments using just ASIO4ALL and the onboard audio. 

Same problem here. Clearly Dell fault, no problem in Linux but with W10 audio quality is terrible.

Im using the Focusrite 6 Usb interface (2.0) that worked without any problems on my old samsung laptop. In my new Dell 9570, I get constant clicks and pops. THe plugin GTR 3.5 by waves that I use to play guitar generates a lot of noise (there was none in my old Samsung laptop - it was clear and beautiful audio). And just now I was working writing music on Sibelius with my midi keyboard and out of nowhere, the sound of the key input stopped - had to reinitialize the program. I have to keep the buffer size very high to work with audio programs, wich is bad for playing, recording, etc... I've bought this new laptop to get better performance but there are a LOT of this audio problems....

I confirm clicks and pops using an external audio device as well. Currently using Focusrite Scarlett 2i2 2nd Gen.

Audio latency is good, but those dpc latency bursts keep causing clicks and pops. OK, the issue may not be blocking but is definitely annoying.

Why can't this laptop just work as intended?

This is my LatencyMON report:

And now my turn... Same issue here ! XPS 15 9570 i5-8300h.

Not even possible to line up to tracks in ableton !
While my 10 years old laptop does the job with 12 tracks and 4 returns with full of effects and postprocessings. Difficult to understand... !

Very dissapointed. Do something Dell !

Same issues here. Very frustrated. 

I'm getting around 1.7 to 1.9 ms on the proces ACPI.sys as shown in my  LatencyMon tests while recording. 

Please fix this. We can work our way around temporary solutions, but it needs to be adressed by the dell developers!
