hi ...
i've got an maudio usb quattro recently but i've got some problems with it... i know, some people on this list are working with this device, so maybe someone had this problem, too ...
running pd i get dio errors, either "DAC blocked" or "ADC blocked". i get there messages about once a minute.
i'm using alsa (0.9.2) with a .asoundrc file and i start pd with -alsa -alsadev quattro.
thanks ... tim
