Re: Sound issues on dual-boot machine

This sounds rather incredible (to me at least) but here's what I've done to confirm this. Initialisation :) Your soundcard needs initialising before it'll function in some way that linux understands and FreeBSD does not, once linux has done the dirty the card is then alive and kicking. I have a similar issue with my wifi card and FreeBSD/Win2k dual booting, when i boot into bsd from cold all is well, if i boot into windows first and then go back to freebsd without a shutdown the cards isnt there, windows does something to my cardbus controler that stops it initialising properly under bsd, good thing i only boot win2k for ghosting :) - Mike Woods IT Technician ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Hurm. That's all well and good, I guess, but *why* is Linux initializing the on-board sound while FreeBSD is/can not? I admit my understanding of PC hardware to be limited, but I had thought that the purpose of the BIOS was to initialize the hardware for the OS to recognize. Doesn't it hand out IRQs and so forth? Is my problem indicative of a general driver deficiency in FreeBSD? Is there some module I'm not aware of that, were I to load it, take care of this mysterious initialization? --Damon ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

The bios is more like a wakeup call, it tells things that need to be told to wake up and say hello, anything after that is up to the hardware, more than likley it's a quirk in the particular peice of hardware, something about the way it works that differes just enough from the norm to need special attention to get it going.

No, this looks like a device specific quirk, like how the 3com 905c will always try and share irq's with my soundcard in my home machine regardless of anything i do yet in other machines it behaves itself :) With the sheer amount of hardware and variations on hardware available these things are to be occasionaly expected :) - Mike Woods IT Technician ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

A disappointing answer, to be sure :-( A thousand thanks for your explanations, however. :-) --Damon ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
