Comment (by ttcoder):
... or if 'talking directly to the driver' (as mentionned by korli, thx!)
is not too much of a hair-puller maybe I can take a stab at that... This
would make sense especially if implementing the Media-Kit/multiaudio <->
driver glue is enough work that it won't happen anytime soon...
@korli I wonder how to talk to the driver: presumably it exposes 'ports'
to the userland world, so in my application I would call find_port() on a
hardcoded name (?), then talk it into selecting the specific "node" (for a
given audio jack of my choosing) and send audio data to that same port ?
In truth I'm much tempted to let Sean & Dane organize a bounty ..etc to
allow you to finish that aspect of the driver.. Though then I would
''still'' have to figure out the multi-audio API of course (it's not at
api.haiku-os.org)... If you're sure I can dive into the header files
(which ones, the HDA driver's, not the Media Kit's, right?) and have
something to show for it when Dane asks, I'm all for it ;-)
[to recall my non-userland track record: my "skills" are limited to having
fixed a bug in the HDA driver for my R61 thinkpad, and even that "bugfix"
was done with brute force tracing, not actual understanding of the driver
or the media kit internals]
