D1194 sound problem

Postby blowkj » Wed Jul 30, 2003 17:39

I have a Euroline PC with a D1194 motherboard carrying onboard AC'97 sound. There is a problem which seems to be an interaction between the sound and the IDE, after several days of work and particularly use of sound, the hard disk thrashes, system response is negligible and sometimes sound playback gets looped which is very irritating.<BR>I have had the same problems using the supplied ME (which I hated), an old copy of 98SE and now Linux (Debian 2.4.18). Given the variety of OS's suffering the problem it must either be a hardware problem or a BIOS problem. Anyone had any similar experience?

Looping Sound looks like an Interrupt Problem to me.<P>Have you treid disabling the sound and the problem went away or why are you so sure it's the AC97?<P>What Cards do you have installed besides the graphics card? In which PCI slots?<P>Look in the manual<BR> <A HREF="http://manuals.fujitsu-siemens.com/PERIDOCS/SYSBOARD/A26361-D1194-Z120-UK.PDF" TARGET=_blank>http://manuals.fujitsu-siemens.com/PERIDOCS/SYSBOARD/A26361-D1194-Z120-UK.PDF</A> <P>On Page #7 you have the interrupt sharing table. Only read the first Letter for each device / slot. All Devices / slots with the same letter share an INT line and thus share an IRQ:<P>A: AGP, GraphicsProcessor, PCI#4<P>B: AC97, SMBUS, PCI#1, PCI#5<P>C: PCI#2<P>D: PCI#3, USB, LAN<P>So if you have only one PCI card insert it in PCI#2 and it will get a unshared Interrupt. <P>If you have multiple PCI cards place the most critical card there, like TV card, Creative Labs Soundblaster Cards etc. <P>In PCI#4 place only cards which need no interrupt, but preferrably leave it free.<P>By the way: the newest BIOS is 1.09, available here: <A HREF="http://www.fsc-pc.de/support/Description.asp?drvid=22735" TARGET=_blank>http://www.fsc-pc.de/support/Description.asp?drvid=22735</A>

OK, so I've installed the latest 1.09 BIOS and started using sound again. Of course I won't be sure about anything until a few days have gone by as it usually takes that long for things to stop working.<BR>More when anything happens...

No better now. In fact enabling sound really makes a mess of things. System crashes after only a few sounds played. Disabled sound and now all OK again.
