Its the driver that does not work with your vendor, the ac97 codec is the same, but the way into it is different for different vendors.
I have had a look for info on your vendor, but can not find any thing. If you can find info on your vendors ac97, let me know and i will have a go at making it work. Even a linux driver in C, will do, but must be the full code not just the ac97.c, which is the same for all the drivers and i have that. \\\\||//// (@@) ASHLEY4. |

HELLO ASHLEY4
have you got a working code to interface a PCI bus? i'm making a PCI card and i'm currently on searching one. |

Hi MATRIX, With what you want to do you would be better looking at info like this:

So you want to use it for commercial usage in embedded systems ? .
I think the GBA make a good starting point, like this: http://www.ziegler.desaign.de/GBA/gba.htm \\\\||//// (@@) ASHLEY4. |

Hi ASHLEY4,
under linux, kernel 2.4.x, my soundcard does work flawlessly with the ALSA driver "snd-intel8x0", in case you dont have it, I attach the source. Also I have a quite detailed pdf-File from Intel, 105 pages / 700 kB, titled "Audio Codec '97", Rev. 2.2, September 2000 - would this be helpful or do you have it already?

Thanks, It will take me about a week for me to make the code for you to try it, but at first glance it looks the same as for intels.
In the mean time try these other peoples code to see if they work, let me know if they do. http://www.programmersheaven.com/zone10/cat592/23237.htm PS: i have the pdf, intel make the best manuals. \\\\||//// (@@) ASHLEY4. Last edited by ASHLEY4 on 19 Dec 2004, 02:38; edited 1 time in total |

WOW - SUCCESS !!!!!!!
Hi ASHLEY4, thanks very much for those codes, I just played an audio CD in DOS on my Notebook with AC97 Audio Codec ichinit worked out of the box and initialized my ICH3 chipset with "Cirrus Logic CS4299 rev D" codec. The 23237 player didn't work out of the box, but I changed two source files to make it detect ICH3 (as suggested in the readme file) and recompiled - success! Together with ichinit (loaded before) (not, if called alone without prior initialization by ichinit!) the player does play 16bit stereo wav samples (as far as I see, only 44100Hz wav files...) So I guess you don't have to do the work Just one last question: Do you, or any of the other readers, know any other wav- (or maybe even midi-) player software for DOS using the AC97 codec besides this 23237 player (as I can only play 16bit stereo 44100Hz wav files at the moment) ?

Hi Cryptus, glad you got it working, the same person that made ichinit, also makes this (MOD/S3M/XM) player with ac97 driver, if thats any help ?.
Not tyred it myself, also when i have time i would be greatfull if you could test my next ver of my ac97 driver to get it to work with your card, i am a bit busy making a floppy driver for my OS. \\\\||//// (@@) ASHLEY4. Last edited by ASHLEY4 on 19 Dec 2004, 02:37; edited 1 time in total |

Thanks again ASHLEY4,
going to test the player tomorrow If you need me for your testing reasons, and I'm not that present in the forum, don't hesitate to mail me: cryptus[AT]cryptus.de Frank |

just tested jp.exe (judas player) - not at all satisfying, as:
under plain M$-DOS it plays (only) mod/s3m/xm-Files with (roughly) about 5-10times of the normal speed (kind of "Donald-Duck-sound"...) regardless of any added options, and under FreeDOS or DR-DOS it gives a hardware init failure... (while the 23237-player does work in all tested DOS, but with the limitation of 16bit stereo 44100Hz wav files ...) So any hints about working players for AC97 codec are still welcome... |

You could try here: http://www.micosyen.com/
this is the best dos player i have used, it defaults to SB16, so you need to email the person who made it to see if is interested in adding the ac97 driver. PS: Y do you want to make things work in dos, are you a dos fan . Also this would be a great projet. \\\\||//// (@@) ASHLEY4. |

hmmm, seems to be an mp3-only player? I am more interested in wav/midi, maybe mod too.
As you asked: Actually I am Linux user (in daily life), but interested in DOS too, as I am building multi-bootable CDs with all kinds of OS on, starting from CP/M and DOSPLUS via old and newer PC-/DR-/M$-/Rx-/PTS-/Free-DOS to Linux, but there is also MenuetOS on my latest CDROM An OS is interesting for my project if its not too big, and bootable from CD As I have different soundcards in all my PC's, of course I want this bootable CD to be able to play under all OS.... for 'normal' daily mp3 listening I use linux, of course. |

The OS I am making is like a 32bit pmode DOS, thats Y its called " Dos Extreme" , it can boot from a floppy or CD.

ASHLEY4 24 Oct 2004, 14:53
Soon as i have finished the pmode floppy driver and done the command line, it will be ready for release, and i will let you know .
PS: it was a bit late last night, i should of put "Dos Extreme" "DEX" for short. \\\\||//// (@@) ASHLEY4. |
