Output attenuated on Firewire 410 channels (SOLVED)
Posted: Wed Jan 26, 2011 1:39 am
Trying to trouble shoot a problem with our system. We are currently using SCS 10.7.3 on a Lenonovo PC running XP (SP3) into an M-Audio Firewire 410 via a SIIG firewire PCI card. This has worked fine in the past. Recently however, we can only get normal volume output on channels 1/2. Channels 3-8 appear to be attenuated when I look at the Firewire 410 mixer screen. There's some signal there but not much. Channels 3/4 are almost zero, channels 5-8 very low volume. The SCS output representation indicates it is outputting on all eight channels at the desired levels. I have driven the Firewire 410 from a laptop and it, and everything downstream, appears to work ok.
We have reinstalled SCS from the setup file of SCS 10.7.3 that I retained, also reinstalled the 410 driver and removed and reseated the PCI firewire card. The setup is in a community theatre so others have used the system although it is only used for audio work. In the hope we could find a setting problem left by a previous user we have poked and tweaked various settings in SCS, and as many audio settings in the Windows morass as we can find, but with no success. I did find that I could direct audio from Windows Media Player to any of our eight output channels.
If anyone has suggestions on what we might try to resolve this it would be appreciated.

A younger mind has found a way to solve our problem. We used to set up our devices as Firewire 410 1/2, Firewire 410 3/4, etc and the speaker/output assignments as 1/2 stereo, 3/4 stereo, etc to match the device specification. This no longer appears to work for us.
What does work is to leave the device assignments the same and use 1/2 stereo as the speaker/output for each device. The system also works by choosing only Firewire 410 ASIO as the output device then specifying 1/2, 3/4, 5/6, 7/8 as speaker output assignments.
We still don't know why this change has occured but assume it may have something to do with upgraded M-Audio Firewire drivers.
Again, if anyone has an explanation we'd be interested to hear. It's great that we are back in business but it would be nice to know why!
