I'm trying to get some of the channels working on my Tascam and have noticed that some channels ( like 13 and 14) will get input signal, meters jump, etc, when input metering is engaged. When I track to these channels they seem to be recording, but there is nothing on the playback. I have heard in other forums that these channel cards are notorious for having to be reseated to make a solid connection. I've tried to do that with no luck. Just wondering if anyone has any insight to this problem.
