While I was at work today my wife started trying to connect the Pinnacle 510 to pinnacle software on her windows 11 laptop and when I came home I used my install disc of Pinnacle Studio Plus Version 11 on my windows 7 offline PC. I was able to adjust the audio in Pinnacle Studios. I did a small test capture on a regular VCR.
I then closed Pinnacle Studios and opened crossbar thing. Then I opened my 510’s audio I now can connect and adjust the audio. I have more options than just adjusting the video proc amp.
I opened
Virtualdub 1.9 and did a small test capture. Everything works well now!

I am glad that it is working.
