Intel SST audio

Hi aill,

Can any body tell me, how to write a WDM driver for Audio card which is supporting the Intel’s SST.

Intel SST Audio should be supported by Windows out of the box. Have you
tried it, or are you just getting started?

We are not yet tried any thing, just started.
Actually we have to use the Intel SST for our audio codec, We will use the Intel SST DSP for our audio codec and amplifiers.
Is there any specific explanation about this?

You’ll need to go to Intel for this. So far I haven’t found any
information on SST except for content-free marketing blurbs, but the
information mus exist somewhere.

However, the relevant point here is that, as long as you describe your
SST setup accurately in your ACPI tables, you do not need to write a
driver. Intel’s in-the-box driver will drive your device.

Hi Tim,

Thank you for your response. We are also not found any information regarding the SST.
Can you please point me, how to get the information from Intel (Forums or links etc) and tell us how to setup the proper ACPI tables for our device.

You do what I did, go to Google. Search for “intel smart sound
technology spec”, and the 3rd link is a PDF describing the ACPI table
changes for SST.

How are you hooking up to the SST? In most systems, SST is just part of
the HDAudio endpoint. Are you buying a separate chip with SST? If so,
then you must be going through a manufacturer’s rep. They ought to be
able to connect you to all the technical details.

From the SST to our codec we are using I2S.
Actually we are not getting any information, how to register with the SST driver.

We gone through this document and understood that we need to map our endpoint details to SST, but how to do it? what driver we have to use? How to modify the SST acpi tables?

Are you buying a separate chip with SST?
We are not using any third party vendors chipset, we want to test our codec and amplifiers with SST platform.

OK, I have to admit that I am totally boggled by the virtually
non-existent Intel documentation on SST. I can’t tell whether it is
just a clever marketing term for a fancy new HDAudio chip, or if it’s
actually a hardware standard of some kind providing some new services.
I don’t know why I would want SST in my system, nor where it fits in the
sound circuitry, nor what functions it provides, nor whether it can be
configured or disabled, nor what configuration it has. This is a
dreadful failure on the part of Intel’s marketing, and if there are any
Intel employees listening in, you might forward that on. With one
Google search, I ought to be able to answer the question “what is SST”,
and that’s simply not possible today.

Here is my recommendation to you. I can’t be of any further help, but
there is another mailing list called [wdmaudiodev] where all the cool
audio driver kids hang out, including Matthew van Eerde from the
Microsoft audio team. Matthew is a very bright and very helpful guy who
is “in the know” about Windows audio technology. If anyone knows how
SST plays with Windows, he will know. You can sign up here and then ask
your question:
