ASIO4ALL Buffer Size Problem

Question

I have just upgraded my laptop from a HP ENVY 15-J151sa to a HP ENVY 17-CG0551sa. I am having trouble with the lower buffer size limit when I have my Fender Mustang V2 plugged in (I use the USB for recording guitar direct in) being stuck at 512 samples. This was not an issue that my previous laptop has and it also is present in Ableton as well as Cakewalk. I'm using the same ASIO4ALL driver on each laptop too so I don't think it is a driver compatibility issue. The strange thing is that when the amplifier is not plugged in/is turned off on the driver panel, I can adjust the buffer size however I want.

 Any tips on how to lower the buffer limit on my new PC as the latency at 512 samples is just a bit too high for me to tolerate. I've included some screenshots below to illustrate the problem.

combining interfaces in asio4all will always cause issues, at best you might get reliable performance but only at the ability of the lesser device (higher latency), ideally use only one (in your images, that means disabling either the realtek or the  mustang) - -you may get acceptable performance using both simultaneously via wdm or wasapi driver modes, but i don't have any experience there

good luck!

The only external device I am using is the Fender Mustang amp, the realtek audio device is the onboard headphones/speakers, it shouldnt be a multiple device issue as my previous laptop worked just fine with the exact same set up

fair enough, but bare in mind that the new lappy will have different hardware/drivers so you can't assume it will behave the same... i use asio4all regularly, but only get decent performance if it's just a single device (for me usually the realtek, sometimes an external) - -but i should say i'm assuming the mustang connects via usb?

anyway, in your screenshots you have the playback/recording timing masters set differently on the new laptop - -maybe it's that? try setting them the same as the old one

good luck

Yeah, this is definitely not right. Your Buffer Size in Asio4All and in Cakewalk needs to be sync'd.
