It appears that HSModem V0.87 stops receiving and processing when more than +/- 10 virtual cables are configured.
When the problem occurs, the RX volume graph stays zero in the Setup panel. The PortAudio ID's however, are correctly enumerated on the HsModem console.
Reducing the number of VAC's back to 2 .. 6, and everything is working fine.
I believe this could also be the problem why certain Flex Radio users cannot fire up HSModem.
Can someone maybe confirm this behaviour or reproduce it ?
