[mythtv-users] multiple capture cards and sound?

I had been thinking about getting another capture card (I have only one 
now). Then, it occurred to me that I may have an issue with sound.

I am running a Hauppauge PVR-250 and I'm using my MoBo's on-board sound. If 
I pick up another PVR-250, do I also have to buy a sound card to pair with 
it?
