Hi Brent :) hdspmixer does save and restore all settings correctly on my machine, but alsamixer settings can't be stored for my RME HDSPe AIO. FWIW the extension ".mix" isn't needed. I experienced another issue. If I try to set a fader to 0.0, I only can chose between -0.1 and 0.1, 0.0 isn't available. Regards, Ralf
