I have two laptops running Creator NXT 4: Dell M6500 workstation ("MERLIN"); HP Envy 17 TS ("AVALON")
On MERLIN (Windows 10 x64 Home) everything is fine recording video and audio from my DVR.
On AVALON (Windows 10 x64 Pro) when I start a video recording the AUDIO output using the speaker button on the Capture control panel drops by 10+ dB.
This lowered sound level is reflected in the captured file (on AVALON and played back on another system).
I did a Hard Reset on AVALON and tried the latest audio drivers via Windows update.
Device Manager shows Roxio (and everything else) as using the Microsoft driver 3/17/2017 10.0.15063.0.
Same issue remains.
Prior to 22-Mar-2017 everything on AVALON was fine - I assume there was some Windows Update since then that maybe the culprit, but MERLIN is running a similar driver (via Microsoft migration / update) but has no problems: 7/15/2016 10.0.14393.0
According to the HP Support site: sp63555.exe which it labels as IDT 6.10.6491.0 audio driver files are the correct ones for my system, but these do not appear to be installable (I made multiple attempts; it runs to completion, I reboot, but nothing seems to change).
AVALON also has Beats Audio if that could at issue.
I don't have a clue how to force AVALON to accept a different AUDIO driver over its apparent reluctance in hanging onto the MS version cited above.
Not even sure it that is the issue.
