Subject: YMF724 From: newsham@lava.net (Tim Newsham) Date: Tue, 18 Jan 2000 22:32:10 -1000 (HST) [is this the right place for sound device driver issues?] Hi, I have a YMF724 based sound card (yamaha chip). It has an OPL3 and SB emulation on the legacy audio block, as well as a "pci audio block" which promises direct audio access. I got the tech sheets from yamaha's site for the 724 (and the 754 which supersedes it), but neither describes the "pci audio block". It is trivial to turn on the legacy audio block, and after doing so, it is possible to load the opl3 and sb drivers (sb only emulates up to 3.01, however). Upon doing so, I can use the opl3 synthesizer fine, but playing audio through the sb driver does not produce any audio output (although it seems to take about the right time.. ie. no hangs, irqs working properly?). Any ideas why the sb driver's output would be silent? This is a PCI card emulating the legacy ISA SB card, are there any weird issues with DMA that I should be aware of? Has anyone had luck getting specs for the pci audio block from yamaha? === Subject: Re: YMF724 From: "Gaillard Lee Johnson--www.imyourhandiman.com" <lee@imyourhandiman.com> Date: Wed, 19 Jan 2000 06:02:42 -0500 hi anyone.. i was wondering i am having troubles getting my sound modules to load at bootup.. i've done all i can think of.. added section ( according to howto's etc.etc.) in conf.modules addeds section ( according to howtos again) in rc.sysinit i think it is..... did all the make xconfig stuff to make sure i had things correct and saved... did all the make....stuff correctly ending with make bzlilo when system reboots just says loading sound modules then..unable to load module somethings amiss somewhere and i can't tell where thanks lee === Subject: Re: YMF724 From: newsham@lava.net (Tim Newsham) Date: Wed, 19 Jan 2000 00:19:06 -1000 (HST) > > hi tim.. > > i was wondering according to my computer vendor i have a YMF-740 :)..hey > you're the first person i''ve come across that matches so close to what > i have...I wonder if what you've done should work with mine..what's this > about turning on varoius blocks > this is news to me..?..:) > > something i should be aware of i wonder as regards to getting to work > better in linux? The turning on blocks thing is about programming to the chip directly in the device driver. You cant directly use a YMF724 chip with linux right now. Someone needs to write a device driver for it. I dont know about YMF740, but I dont know if such a thing exists, your vendor might have made a mistake? I dunno. === Subject: Re: YMF724 From: Alan Cox <alan@lxorguk.ukuu.org.uk> Date: Wed, 19 Jan 2000 11:55:05 +0000 (GMT) > Any ideas why the sb driver's output would be silent?

No, nor getting the ISA compatibility mode working. ===
