Greetings! I saw Qmod on a facebook group so thought I would give it a try.
PC - i3-4170, 4GB RAM, Windows 7 64 bit, M-Audio Audiophile 192 Sound Card. Avid user of ST, BAOne, Breakaway Broadcast (not at the same time, machine configured to take audio in and send MPX out). Installation of Qmod appears successful, the other software is successfully working.
I have had some success getting RDS to work but no success getting clear audio. Sounds like computer noise, modulating at full level, do get a hint of audio in the background. The audio appears to be hitting detected by the processor, the meters move appropriately. Attached a screen shot of my settings and will see if I can add some audio.
