midi works tho' audio is dead

The Yamaha AW4416 came back some weeks back after a stint at Chennai, with no improvement. Apparently it can't be fixed without a high cost. The audio output is dead, and I believe the inputs are dead too. Some of the switches are also not working. Tested the midi connections today by connecting to laptop like in my previous post through a Tascam US-144. The Midi section seems to be fine. They seem to be getting a firewire mixer at the Studio. Then maybe I will get the Tascam US-1641 once again.
