Hi HDA developers,

	I am trying to write a small tool for control and analyze HDA 
codecs (something like more powerful GUI brother for Takashi's hda-verb). 
For rapid development, I chose python and pygtk2 gtk bindings. At this 
time, only basic things are implemented and not all widget types are 
supported in detail, but routing and volume control is implemented. If you 
are interested to check this preview and send me ideas to make this tool 
better, the code is available at URL bellow (or in alsa.git repo - see 


Planned features:

- support all widget types in detail
- allow assign custom names to nodes for better orientation
- raw verb r/w ops
- save a text output of codec configuration for driver developers
  (maybe some diff)
- run aplay or speaker-test directly from GUI
- run arecord directly from GUI with some simple scope to analyze input
- sysfs support for actual HDA driver
