Hi All,

 

For some time now, I have had issues with the Conexant ISST Audio driver. From time to time Windows 10/pro freezes for a short time, during this time I can see that flow.exe (C:\Program Files\CONEXANT\Flow) is using about 20% of the CPU. It should be noted that after a few minutes the CPU usage of flow.exe goes back to normal.

 

When no sounds are being played thought the Conexant sound card everything works fine.

 

Application that are being used during the audio the freeze are: foobar for some background music, skype for business and pidgin. Then opening new tabs in firefox (57) causes these freezes.

 

HW: ProBook 640 G3 i5-7200 16GB RAM.
All firmware and drivers are up to date.
Conexant ISST Audio: Driver date 2017-09-04 Driver version 9.0.164.0

I have tried the following:

Remove driver from add/remove programs. Windows found it again.
Remove driver from device manager, again Windows re-installed again.

 

What has help a little was to disable all sound processing via the volume mixer (Enhancement tab – System Effects Configuration)

 

 

 

Regards

Nikolay
