Hello, I have an older version MC24 that is having some issues with the volume control on top left side. I just added a Jlsounds I2S to USB and downloaded the latest drivers. The volume control does not work at all using this Jlsounds board! I have to get up and manually turn the volume up/down on my preamp. Can anyone here help me fix this issue? And also when I use my cursor to try and adjust the volume on MC, it stalls and flickers? Thanks!
