Announcement   Announcement : New AHI driver for AmigaOS4
   posted by geen_naam on 31-Mar-2021 23:00:51 (1994 reads)
April 1st, 2021:

I am pleased to announce the immediate availability of a new AHI driver for AmigaOS4.1. This driver supports PCIe soundcards that comply with the Intel HD Audio (Azalia) specification.

Analog recording ( for now 16bit up to 192kHz) as well as analog playback (up to 7.1 channels and up to 32bit/384kHz) are supported. Support for digital inputs and outputs is planned for a next release.

AHI prefs offers both 16bit and 32bit HIFI modes. These modes basically determine what audio resolution goes into AHI. The output of the AHI HIFI mixing routine will always be 32bit. This driver will automatically select the best available resolution for playback.

A basic mixer tool is included to provide volume control.

Which cards do work (verified):
- Creative Labs Soundblaster Audigy FX (24bit/192kHz 5.1)
- Startech PEXSOUND7CH (24bit/192kHz 7.1) -> Available under many different brands
- Fransande 411944 (24bit/192kHz 7.1) -> Available under many different brands

Cards that should work:
- Terratec AUREON 7.1 PCIe (will arive shortly for verfication)
- Basically every combination of HDaudio controllers and HD audio multichannel codecs (eg. CA0113, CM8828, CM8888, CM9882A ALC898 etc)

Older cards that might work (no guarantees):
- Asus Xonar Phoebus solo (CM8888 in combination with high quality discrete DACs)
- Powercolor Devil HDX (CM8888 in combination with discrete DACs)

Cards that do not work (yet):
- Core3d (CA0132) based Sound Blasters (Eg Z, AE-5, AE-7, AE-9 etc). These cards have a DSP (ca0132) instead of an audio codec. Support is planned but don't hold your breath because extensive and undocumented configuration is required.

Cards that will never work:
- PCIe Asus soundcards that are on sale now. These cards are either AV100 ( rebadged CMI8788), CM8786 or C-media 6632AX (USB chip) based. Neither of these chips comply with the Intel HDaudio standard.
- Sound blaster Audigy RX and all other EMU based or X-FI based sound blasters. (do not comply with the Intel HD audio standard)
- Non-PCIe soundcards in general like external USB cards.

See readme for more information.

The driver is called HDaudio_AHI.lha and is available for download at: OS4Depot

No joke. And it would be wise to read this thread, although you can follow from this point:

Nice with yet another ahi driver.
Thank you.

I think i have one Creative Labs Soundblaster Audigy FX that i can test with.
I'm already happy with the soundcard i use in my X5000 but having another option is good.

@drHirudo

The author will answer questions when he is available. Please see my prior link.

He is currently engaged in assisting to resolve other issues with beta testers and developers.

@drHirudo,

I have no link with the AmigaOS4 developers or beta testers. I'm just a user who was in need of a AHI driver. And happy to share the result with the community. If someone can point me to the documentation than I can always give it a try.

Half of the development time was figuring out how AHI works. So that part is done already

The open PPC Notebook project uses
AUDIO: C-Media 8828 sound chip, audio in and audio out jacks
Open PPC Notebook FAQ

Is that chipset supported?

@billt

I now notice a typo in my text. It is the CM8828 that is supported. The cm8288 doesn't exist. Yes, the notebook uses a CM8828+CM9882A. So this is fully supported. Provided that they do not make a mistake in connecting it all together.

@Sinan.

As far as I know there's already a A1222 driver. I see one included in Enhancer 2.0

You have already done the heavy lifting since AMD HDMI audio is yet another HDA :)

Promote your driver on Facebook amigaos4 group a bit, and made a fancy video of installing/testing it with SB Audigy FX:

Well, we all hope that the engineer did a good job on that!

Thank you for providing your AHI driver for the CM8828, just mentioned here

I just installed a Soundblaster Audigy FX in my X5000 and all I can say is WOW does this driver work and make this card just shine in the machine! I had an ancient Sound blaster Live PCI card in it before and this just puts it to shame.
