Hi Jimmys69:
My computer system is as follows:
Windows Vista Service Pack 2
Compaq computer Intel Pentium(R) Dual CPU 1.86 GHz
RAM 2.0 G
System type 32-bit.
When the audio drops out I unplug the Tascam US-144 USB connection and re-insert it. I do this when Cubase and the project are active. This works most times.
Also, when I have the audio problem, when I try to exit from Cubase it has a problem "Cubase not responding" message. If I click the exit icon (top RH red X button) a few times it eventually exits from Cubase.
Also, on trying to start a new project today Cubase refuses to give me a Mono track. When I ask for Mono I get Stereo. Also, with a guitar plugged in directly (and also a mic) I can clearly hear the audio through my headphones (via the US-144). However, there is no signal in Cubase. The mixer channels/sliders show no audio. However, if I try to add a Mono track to an existing project it delivers OK. If I had any hair I would pull it out!!
