Hi,
In the process of debuging the problems some hdsp users are experiencing, I reviewed almost every single line of code in the hdsp driver, and there are things in there that were inherited from the old rme9652 driver and that don't seem relevant anymore for the hdsp (particularly now that hdspmixer is there).
* Does anyone use the passthru control ? If not I would gladly remove it as it interferes with hdspmixer. Anyway everything it did can be done with hdspmixer or the Mixer control using a shell script.
* The current behaviour is that the driver cancels any 1:1 input to output routing when playback or capture is enabled. Not only this interferes with hdspmixer, but I find it rather confusing. Any objection to a change here also ?
I have never used it. ANything that simplifies the driver is good.
I also realized communicating with RME that the firmware files we use in linux are not the same as those used in current versions of the windows and mac drivers. As a consequence people using dual boot systems should always power cycle their iobox when switching operating systems to prevent any problem (this is of particular importance to rev 0xa users).
This minor issue will be resolved shortly as I'm working on switching to those files for the linux driver. The new firmware files seem to be revision independant (but they do require a driver modification) and add support for disconnect mode (standalone operation of the iobox - I have it working here, it's awesome !)
How does that work? You just set up the routing and it stays there while the box has power?
Exactly. The box can then act as a standalone digital converter for example, or as a patchbay. While in disconnect mode and if you still have the card connected to the computer, you can use hdspmixer for metering, but changes to the matrix mixer (or to any card register) will be ignored. I still have to integrate explicit support for disconnect mode to hdspmixer and hdspconf, but it already works nicely.
