Havent seen this news on Amigans.net yet!

X1000 HDAudio Driver is complete.

Hyperion announce the release of the finished HDAudio driver for the AmigaOne X1000!

The driver now supports recording as well as playback. It also now supports S/PDIF optical output.

This is great news. And one less thing for x1000 "haters" to complain about.

Lyle has done a great job on this.

Thanks, but in truth I am just the last runner in the relay race.
Davy, AlexC, and Rene did the biggest part of the driver.

It is good to have it working though.

My wife says all future projects will be limited to eight hours daily.
It think she missed me.

After that mammoth, I'm surprised she is ever going to let you code again :)

I hope the Envy24HT-Driver will be updated to this level. Would be great for SAM460ex-Users.

@LyleHaze
Just out of curiosity, would the work done on this driver make it easier to write new audio drivers for OS4? (I'm wondering if the code for previous audio drivers was kept private by whoever wrote it, or otherwise was an unusable mess, but this driver could be used as a "template" for future drivers?)

@ChrisH

Most of the previous drivers would not compile on my standard SDK installation. Because of this I assumed that they were cross-compiled from another system.

I later found out that they HAD been compiled natively, but they required some compiler tools and configuration files that I am not familiar with. There was also at least one tool that was missing completely. We had no way to generate modefiles, and no documentation on how they are formatted. One of the things I did accomplish was to write an audio modefile generator that works from a (very) simple text source file to generate Modefiles. The programmer just describes the desired modefile contents and lets the tool create the modefile as part of "make".

Creating newer drivers might benefit, because "hdaudio" is the new standard, intended to replace AC97. One of the design goals was to make all hdaudio chips compatible with a single driver. I will NOT claim that this driver is universally compatible (I had enough of a challenge getting it to work right on ONE!) But it should provide a good starting point for other hdaudio chips to come.

Once I realized that hdaudio was really a "common interface", I found and studied the official intel "master document" for HDAudio, which went a long way towards filling in some missing details from the datasheet for the 92HD700 chip we are using.

There are a few PC speakers or 2.1 with optical input if 5.1 set-up is not needed.

Just making user(s) aware as optical input on 2 or 2.1 speakers set-up are not that common and is normally found on 5.1 or above speakers set-up.
