Installed on HP Pavillion laptop, Audio issues

I have replaced Windows 10 on my HP Pavilion DV6700 laptop with NomadBSD. It runs much better. But, doesn’t find my Altec Lansing audio.
anybody know what audio driver I need to install, and how to install it?

post duplicates:

the OS does not see the device, a new driver may be necessary.
