Windows 10: Kernel Streaming and WaveRT Buffer Size - Differences between Win7 and Win10

I use Ableton to apply a Finite Impulse Response (FIR) filter correction to Windows Sound Mapper Audio. I'm using Synchronous Audio Router (SAR) to create a synthetic ASIO sound device to capture the Sound Mapper output and route it to Ableton where the FIR filter can be applied prior to sending it to a Roland Octa-capture and then to speakers.


Under Win7, I was able to use an ASIO buffer size of 1536 samples at 192kHz. This buffer size guaranteed glitch free audio through the signal path. Under Win10, however, attempting to use an ASIO buffer size of 1536 samples results in horrible continuous buffer underruns, almost as if something on the Windows side (KS or WaveRT) is imposing a buffer size limitation of less than 8ms. I can reduce the ASIO buffer size to 1024 samples and get "almost glitch free" audio, but "almost" isn't good enough and smaller buffer sizes result in even more glitchiness. Reducing the sample rate doesn't help.


I've read everything I can find regarding how KS and WaveRT are employed in Windows, but I was unable to find any acknowledged differences in the implementation between Win7 and Win10. It's obvious something has changed and a lot of people have complained about Win10 audio glitches that weren't present in Win7, but I'm not aware that anyone has come out and said, "Yes; Win10 is different and here's how to fix it..."


Has anyone run into this problem and found a fix?


Thanks!

homegroup win10 not recognize printer & scanner on win7 computer

Thank you so much for the quick response to my problem.

my devices I am trying to access on the win7 computer are:

Printer: Stylus Photo R200

Scanner: Perfection 4180

I had these originally on my computer B4 win10 install. After the install they did not work. That is why I connected to my other win7 computer. The win7 is within my Homegroup and when I access thru win10 I get access to docs, picts, videos, etc but not
the above devices. Reversing this, accessing my win10 computer from the win7, I get the icon my Epson Workforce 310 printer which I set up on the win7 computer for printing as well as the above devices.

Went to Epson website on the win7 comp & found the recommended driver for win7. Did the same on the win10 comp to find drivers for win10. (Did not update these drivers yet.) Apparently they have 2 different drivers dependent on WIN version. Both drivers
are up to date.

Is it possible the drivers are not compatible and this accounts for these devices not showing up on the win10 machine? Don't know if win10 driver will work on win7. I may try to set these up on win10 machine. If work can upgrade win7 to win10.

I tried steps 1 & 2. Step 3, I know I have devices set to show on the network.

Any other suggestions/comments??

 

Buffering on Windows 10 is giving me a headache. Please help

Hello David,

There are multiple reasons why your Movies and TV app buffers. I would like to know more information to isolate the concern:

• When did it start?
• What changes have you made prior to the issue.
• Is this happening to other streaming apps, like YouTube, Netflix, etc.?

In the meantime, I suggest that you perform the troubleshooting steps in this
article to isolate the issue.

We will wait for your response.

Regards.

 

HP Stream & Win10

The 32Gb memory on the HP Stream is not big enough to accommodate all the Win10 updates. How can I reduce the size of Win10 to say 20Gb?
