I would like to connect the following to my PC:
1. Headphones (3.5mm jack)
2. Onkyo HT-R510 Receiver - variety of inputs available, including optical and RCA - used for watching Neflix on home theatre and other similar applications)
3. Onkyo TX-SR507 Receiver - limited to RCA input, used to listen to iTunes on home audio system
Can you please recommend an Audio Card that would work for all three?
