In host or VmWarePlayer machine it works (Win7 - sound recording tool, Skype, Win settings test etc.). Uninstallation of Intel HD audio driver caused automatic installation after restart, but it did not help.

Please try to record sound using Intel HD Audio analogue microphone in fresh Win7 x64 guest in VB 5.1.28.
