Older versions of AHI drivers...

[Karlos]

Hi,

Does anybody know where to find previous versions of the ahi drivers - in particular the paula.audio?

I'm currently using ahi.device 5.33 with paula.audio 4.20 and no matter how I tinker with the settings, the above drivers really torture my 040/BlizPPC.

I can play mp3 etc fine, the problem is that AHI itself seems to hog the CPU rendering the rest of the system sluggish and unresponsive.

Im pretty sure its not the actual mp3 decode itself since playing mp3 streams through mpega (without ahi) is a breeze, playing them via ahi causes the same responsiveness problems as AmigaAmp...

Even the non-hifi modes seem processor hungry.
This wasnt always the case. I can recall having absolutely no problems with older versions of the ahi system (v4.x) - I recall there were calibrated fast modes and they were absolutely fine..

Anybody know where I could get older versions from?

Tried Paula DMA modes?

If I remember correctly you can do a search using google for "Amiga AHI" and it will result a old page that still has the old drivers on it. Give it a try.

Well, I dont really want to use 8-bit output. It is low latency but the sound is pretty nasty :-)

The processor overhead of the old paula 14-bit Fast calibrated stereo++ modes was not a problem.
I could work away, listen to 14 bit calibrated audio and it was all happy.

Since 'upgrading' my ahi drivers, using any (non DMA) output seems to strangle the system. Entering text in gold ed or storm ed actually lags to the point that letters appear a second or two after you type!
You can imagine the typos this causes :-)

@Acill

Thanks, I'll give it a go

I still have AHI 4.14 with paula 4.13 if you can't find it any where else.

Well, I just totally removed ahi and installed an older version I found that still looks a bit newer than yours

ahi.device 4.180
paula.audio 4.23

Anyhow, they are working great and my amiga can breathe again.

Hmmm... Its a bit wierd that the newer version is giving problems. What sort of hardware are you using for sound? Is it a Mediator system or a real Amiga audio card?

Hello,

Yeah i had the same trouble as well. AHI v5 used to eat up lots of memory, processing power and even hang the machine sometimes. Not to mention poor sound quality. So i reinstalled again with AHI v4 on the AHI download page:

Plus i also got the latest Paula audio drivers:

I think that AHI v5 was very bugged indeed. I know this problem has basically been solved, i hope this helps anyhow.

use ahi 4.16 from the official ahi website , dont use the 5.0 stuff unless you are an pegasos user with mos , the ahi5.x eats cpu power like a windows based app

cheers

Yep! Thats what i got. Plus the latest Paula audio! Don't forget that! Very important indeed! :-) And i also use the AHI prefs version from Amiga OS 3.9.
