Question
We wanted to test a MIDI keyboard with the K7VZA motherboard, but we can't make it work at all. With the P6IWP-Fe motherboard (C-Media sound chip) we have no problems. But on K7VZA there is VIA AC97 Audio Codec.


Answer
K7VZA has AC97 codec that doesn't support MIDI device. The CMI8x38 on the P6IWP-Fe has a C-Media chip that does support MIDI device; this is a specification limitation.


Question
The system froze when the sound card was plugged into one of the PCI slot. Please confirm whether there are two capacitors(C31,C32) under the DIMM slot near the right side of the IDE connector. Please confirm if the value of C31 and C32 are 22pf. Can we patch one or two boards with the C31/C32 for this customer to verify?


Answer
The value of C31 and C32 are 22pf. You have to patch them onto the board to fix the problem.
