Intel HD Audio (Azalia) AHI driver for AmigaOS4 (C) H Kanning
-----------------------------------------------------------------------

This driver supports PCIe soundcards that comply with the Intel HD Audio
(Azalia) specification. See user manual for supported soundcards

Analog playback:
- Up to 32bit (Best resolution automatically selected by driver)
- Up to 384kHz  
- Up to 8 channels (Also known as 7.1)
 
Digital playback
- LPCM (No digital formats like AC3 or DTS -> bitstreams not supported by AHI)
- Up to 24bit (Best resolution automatically selected by driver)
- Up to 192kHz
- Stereo (Also when 7.1 mode selected)

Analog recording:
- Either 16 bit (16bit audiomode) or 24bit (32 bit audiomode)
- Up to 192kHz  
- Stereo (Line In) or dual channel mono (Microphone)

!!! Always use the HDMixer and HDMixer.Docky that are supllied with the driver.
Older versions might not be compatible. !!!

The driver has been tested on:
- X5000/20 running Amigaos4.1FE Upd2.
- X1000 running  Amigaos4.1FE Upd2. ( Many thanks to Raziel )
- SAM440EP-FLEX running Amigaos4.1FE Upd2 with startech PCI1PEX1 adapter
- SAM460CR running amigaos4.1FE Upd2.

-----------------------------------------------------------------------
Limitations:
- Digital inputs are not supported
- Sound Blaster FX V2: ALC1220 dsd256 is not supported. The ALC1220 support no
real dsd but consists of "on the fly" dsd<->PCM conversion.
- Sound Blaster FX V2: Monitor volume can only be controlled with the "Monitor
slider" The "volume slider" has no effect because the codec has digital volume
control in front of the DACs instead of analog volume control at the output
multiplexer.
- Sound blaster FX V2: Monitor output to the HDA front panel headphone output
doesn't work. Looks like a bug in the alc1220 codec. I could implement a
workaround by routing "line out" to "front HP" as well. But this means that the
outputs are not individual selectable anymore in the AHI/sound prefs. 

-----------------------------------------------------------------------
Requirements:

- AmigaOS4.1 FE Upd2 (might work on older versions but this is not tested)
- AHI6.6

-----------------------------------------------------------------------

History:
6.11: (28 Jan 2023)
- Added autoswitch for recording buffer format
- Removed Mixer option to limit Recording resolution to 16bit.
- Added X1000 support
- Created User Manual
- Small optimizations

6.10: (08 Jan 2023)
- Added Mixer option to limit Recording resolution to 16bit. This is required
for programs which do not work with larger recording resolutions (Eg. HD-Rec and
AE4)
- Added additional Tooltypes for the Docky to position the docky window

6.9: (12 Dec 2022)
 - Added support for Sound Blaster Audigy FX (V2) (alc1220 based). This is the
best card supported to date with a SNR of 120dB
 - Added Install script
 - Added Titlebar Docky
 - Added workaround for AHI quirk that always selects a monitor input '0' and
control monitor volume when you want to play a sound. This can potentially
result in a lot of noise when playing sounds -> Added "Mute inputs" as monitor
input 0
 - Small speed improvements

6.8: (12 Jul 2021)
 - Added Output selection (ALL, Line, Front HP, S/PDIF)
 - Added S/PDIF out support ( Both RCA and Optical) 
 - Added Output Mute support (Mutes Line, Front HP, and S/PDIF)
 - Added Line In and Microphone Pre-Amplifier support. (From a CODEC
perspecitive, Line In and MIC are equal. So Pre-Amps can be enabled for Line In
as well)

 - Bug fixes (Recording source Selection)
