Comment (by ttcoder):
Just noticed tickets #6514 and #9477. The former (6514) might be already
implemented in the media infrastructure used in Haiku in the last few
years.
The latter is interesting and relevant to this ticket: 9477 starts from
the claim/fact that flexible routing of outputs is already implemented (I
don't have an Echo Layla 3G to test that claim, but things certainly work
well when I hack the HDA driver to provide support ;-), and focuses on
usability fine-tuning advices..
The take-away for me are..
- if the "Output channel mapping" panel of Media Preferences is the GUI
we're looking for, maybe I can later get rid of the kernel/hda.settings
configuration file my hacked driver is currently using. In fact, maybe
those settings are ''already'' applied to my hacked HDA driver we're
currently using in production ? (note to self: if said settings ever get
corrupted, that would explain why we sometimes see one output get silent).
- if (as per this ticket) we bring HDA in line with multi-audio, we could
follow the lead of the Echo Layla 3G driver (presumably that's
`/boot/system/add-ons/kernel/drivers/bin/echo3g`), we could make the same
decisions it made ..etc (hoping they are compatible with what we need here
at TT Systems, i.e. separate outputs for "broadcast audio" and "general
audio").
