It uses the CM108 chip.
The schematic is at:

I only have experience with the DRA (MastersCommunications) sound cards with the C-Media chip (119) and PTT via RA adapter.
All four of my DRA¡¯s (different models) all work: DRA 70, DRA SR.
Will a DigiRig work using a COM port for PTT?
What about a SignaLink (left channel only) and simple VOX for PTT?
The PTT signal is coming over the pin13 on the C-Media chip.
Be sure any auxilary VOX circuit on the sound card is DISABLED!
DRA¡¯s do this with a jumper plug - disconnects the VOX on the LEFT channel or RIGHT channel (another plug to choose)
Can you post the schematic of the ¡°Dinah Sound Card¡±?
Which C-Media chip does it use?
Something is clearly amiss.
Does the rig and Fldigi work with ¡°other¡± sound cards (SignaLink, Rigblaster, etc.)?
