Sonic Solutions file PxHlpa64.sys needs update for Core Isol... - HP Support Community

Bobm65 · ‎09-26-2022

The file that Core Isolation names is: program files (x64)\Common Files\Sonic Shared\PX Drivers\ PxHlpa64.sys. This is a Sonic Solution file . The problem is the program is not listed as Sonic. HP must have adapted this to their system. I removed the driver to a memory stick but no change so put it back now. Called Microsoft, since I felt it was one of their updated that caused this but after working on this for several hours they gave up. Tried to contact Sonic Solutions but they have not answered back. The registry lists a bunch of entries for spatial audio and entires with Adobe and some with Media Center. Haven't been able to find an update on line.
