3810.0. "Soundblaster and IRQs" by ANNECY::HOTCHKISS () Mon Apr 28 1997 09:56

    Here is a puzzle for PC experts.
    I have a soundblaster and win95.It will autoinstall OK and assign
    itself a config that works (IRQ5 etc - all the standard ones).
    I can usually play MIDI and wav files ok.Suddenly,it will stop playing
    wav files.If I then look at MSD (either under win95 or DOS),I see that
    IRQ5 is not detected but is assigned to LPT2(standard).
    If I then force the resource assignment to use another IRQ (like 10),it
    will work again and then after a couple of minutes it will stop playing
    wav again.Midi always seems to work.
    What on earth is going one here.Why can't it detect IRQ5 - maybe this
    is irrelevant though.
    Clues?

3810.1	Plug and Pray!	PCBUOA::WHITEC	Parrot_Trooper	`Mon Apr 28 1997 16:20`	11
	is the SB a plug and play type? And does your BIOS allow automatic assignment of Plug and play devices? Check out both of these. Sometimes its a matter of enabling/disabling IRQ assignments manually before it will work consistant. chet
3810.2	all ok	ANNECY::HOTCHKISS		`Mon Apr 28 1997 16:28`	7
	chet, It is an SB PNP and the BIOS is enabled for pnp. The strange thing is the sudden stopping.How come it can't identify an IRQ either? cheers stuart
3810.3	Can you return it for a normal SB?	PCBUOA::WHITEC	Parrot_Trooper	`Mon Apr 28 1997 20:27`	13
	I'm not to familiar with SB PnP.....did it come with a ISA Config Utility? I know of someone that did get that card to work in an old ISA system 486/33 but it took a little time to try all combinations. can you HARD Lock the IRQ/Resources? If so, then do that. Set the IRQ to 5 or 7. And then to into Control Panel/System to see if DEVICE MANAGER shows any conflicts. Good luck, chet

	Yes,I can hard lock an IRQ and I chose 10 (which conflicts with the keyboard but who cares..). The system will then play sound for a while and then stop. However,it is not the card - all diagnostics and tests work fine.
