I'm still waiting for the fix on this, and I haven't tried any workarounds. This is because I've already had a full share of trouble with the HP KMODE BSOD Lockout in the summer. My Conexant driver is 8.65.282.54, which is not one of the affected versions.
However, in the ISST Audio Driver problem description, my UCI*.dll file is uci64a189.dll, and the version is 7.189.0.0, which puts it squarely in the "affected" list.
It's therefore in the typical HP/Microsoft position; namely half-right (or half-wrong), but definitely half-cock.
Anyone else similarly affected, and if so, have you updated? If you have, how, and what happened?
