Write an HDA audio driver and add-on

[axeld]

We need to support HD-Audio chipsets.

Because of the features of this standard, it might be feasible to create a new media add-on for this as well, instead of using the current hmulti-audio add-on.

[ithamar]

just a quick note to officially register that I am working on this driver. It is approaching reasonable usability/stability, and should arrive in SVN pretty soon.

It is using the Haiku multi_audio API, as that seems sufficient for the features supported, and if multi_audio would/will not fit, that would be a good reason to reevaluate this API :)

[axeld]

Since Haiku's multi-audio API is not compatible anyway, that would definitely be the preferred solution :-) Anyway, I guess you don't mind if I assign this ticket to you? There is a "colacoder" user, but I can't find an ithamar in the user list...

[wkornewald]

I added "colacoder" because that was your (Ithamar's) SVN user name and I thought you'd use that for the website, too. I've added "ithamar" to the devs, so you can now accept tickets yourself (just choose "accept ticket").

[ithamar]

Ok, accepted the ticket now. There's already quite some code in SVN, though the driver is far from finished. So many possible audio features to implement.... ;)

HDA does not work on my laptop yet. It does show up as recognized at the Media panel, but without any controls on its control page. I can try to play files, but I get no output. Attached the syslog.

FWIW I don't have sound either at 192khz/24 bits. I'll probably stick the driver to 48khz/16bits for the time being until fixed. The problem might be related to Haiku media kit/addons.

Thanks, when something might work again, let me know I'll try it. I can also test things if you need.
