The first sound velocity in metastable long-lived superfluid 3He-4He mixtures are measured in the temperature range 30-200 mK and the pressure interval 0-20 atm. The metastable state is reached by continuously increasing the 3He concentration in situ due to changing the osmotic and fountain pressure
