ePSXe Save State Sound Problem Need Help

Hi, I'm currently playing Harvest Moon BTN on ePSXe. Previously, I played with no sound, where I turn it off at the sound setting. Then I started to play it and I saved it into Slot 1 (where my current save goes). I didn't save any back up with save with sound is enable in the setting. So, can I get back the save state work with sound? Because I tried to enable it back at the sound setting, played it but still got no sound. Any help on this problem? Many thanks guys :)
