Azalia?

[bugs]

Will ASIO4All work with the new Intel Azalia chip set?

[Michael Tippach]

Azalia is just a new sort-of-codec-independent audio standard, the natural evolution of AC97, so to speak

The current High Definition Audio driver supplied by Microsoft should work with ASIO4ALL on Windows XP/2000 platforms.

OTOH, the Azalia Spec. also reflects the upcoming WaveRT architecture which is supposed to be introduced with Longhorn. WaveRT support in general is designed into the ASIO4ALL v2 code base, but not fully implemented yet due to the lack of additional information and a testing platform to begin with.

Hi,

I investigate a little bit around Azalia and high definition audio. In my opinion situation is not very
mature, so to speak.
I obtained some result from an Asus mather board P5GDC-V with a CMI 9880.
At the beginning with all drivers supplied by Asus installed I experienced a lot of problem.
Notice that drivers for high definition audio supplied by C-Media or Realtek are divided in two parts a low level drivers produced by Microsoft, but never official released, named …high definition audio accelerator…. and a parts produced by C-Media, Realtek and so on, working around chip setting with graphical support an other.
Well typically you can encounter two different kind of problems:
First: ASIO4ALL hang at every hosting program ( Live, Cubase, and others) start up
Two: also if don’t hang, latency remain in any case very very high whit no possibility to reduce it.
Working around I found some solution:
Firs: Uninstall all drivers for audio support, low and high level.
Two: Request an hotfix to Microsoft for low level drivers for high definition audio named KB832221 and install it. That is very easy to do. Microsoft is very agreeable from this point of view. At this point ASIO4ALL start working properly don’t you expect exactly all output of C-Media or Relatek because driver aren’t able to see the chip in is total functions but just that supported by HD standard. Now you can use every hosting sequencer or composer yet working with ASIO4ALL and find the beast latency you can reach. At last I experienced a latency not so fast like that obtained with AC97 in the same situation but quite good to work at a good level. In my P5GDC-V with a P4 3 GHz I have 6 ms without glitch or drop or others noises with 2 buffers 304 long .

Have fun, friends and tell me back something.

Gianluca.

Hi Gian,

I would be grateful if you can tell me how you uninstalled the low level and high level drivers from your system. I got the KB835221 hotfix but I am unable to remove all the old drivers.

Thanks

hi Neebo,

in Windows XP you can remove high definition audio drivers in: control panel/application installation. I just removed my drivers (two items high and low level) from this panel without others trouble an then I installed new hotfix. Try and tell me back something.

I have installed Asio4All 2.7 on an asus p5ad2 mainboard (cmi 9880) along with the latest c-media drivers and all works perfectly without having to revert to the MS driver or installing a Hotfix

Latency in reason is 11 ms with 48kHz ... Cool

[Jimbo]

Correction... Latency is now 1 ms
