jack only works in 'playback' mode, none 'duplex' or 'capture' works.

The 4Front OSS driver (now GPL) is working OK.
The driver is implemented in:

oss-v4.0-build1008-src-gpl/kernel/drv/vortex/vortex2.c

inside 4Front OSS source code.

I can do full duplex (capture and play) ok, and jack works ok too.

Closing out old stale bugs. If this is still a problem please re-open the bug and update the version string
