locked PC Audio Output Level decreases during Transmission #AudioIssues #transmit

During a FT4 or FT8 transmission my RF power level decreases/declines from full power to 20% of full power.  When I look at the PC's Sound Settings while transmitting I see that the Master Volume level is decreasing all by itself.  The IC7610's ALC is NOT activating as there is no visible level on the ALC meter.  I had this problem a year or two ago, but 'forgot' how I fixed it.
