I'm running my Mac through a Tascam US-122 USB audio device, which connects to my studio monitors. I finally ditched my hardware mixer which I have always used to control volume. I figured it would be easy to control things via the volume control, however that doesn't work. If I move the volume slider in iTunes, that DOES control volume, but there isn't any easy keyboard command for that. I was hoping hitting the function keys for volume would let me easily move the master volume (sent to the USB device) up or down. There must be some way to make this easy! I would really appreciate any advice.<br />

Thanks,<br />

mac volume control does not control volume connected via USB audio device

Apple's early computers ran on a variety of operating systems, including a Pascal version and one based on CP/M, before releasing its ProDOS with the advent of its 16-bit computer. With the release of the Lisa, which had its own OS, Apple and computing entered the graphical age; it was followed by the Macintosh, which offered a series of "System" operating systems. Other Mac operating systems included PowerPC until Apple acquired NeXT and folded it into the Mac OS. Current operating systems for Apple devices are Mac OS-X and iOS.
