Trying to run two nodes on one Raspberry Pi not working

When I try to run two nodes in one Raspberry Pi and connected to two other nodes I get audio from only one at a time. I can also hear audio from the other connection very weak in the first connection. Any ideas? Thanks. N5CWH Chris

If you could follow up on this, that would be great.
What did you do?

N5CWH,

Did you get this resolved?
