Re: Problem writing to PCM plugin

["Arve Knudsen" <aknuds-1@broadpark.no>]

Based on your suggestion I rewrote the plugin, so it wraps a route plugin.  
And now things work as I would expect. I must say I'm still confused on  
the issue, as I haven't found any explanation why my original approach  
wouldn't work. What's the difference between defining a translation table  
directly inside a "plug" plugin, and aggregating a slave "route" plugin  
within a "plug"?

Sort of weird that the plugin caused an assertion only when used in  
combination with the nForce2 chip, and not the Hammerfall (just silent  
operation).

Thanks
