I've checked the archives and not found anything relating to this problem, so please excuse the interruption if I am in error. I've put together my new machine, using an ASUS A7V8X-X motherboard, and installed FC1. The on-board sound module is detected (accurately, it seems) as a VIA VT8233/A/8235 AC97 chipset. This is consistent with the board manufacturer, who says it's got an ADI 1980 (which the ALSA webpage says uses the 8233/35 chipset and the AC97 CODEC). All well and good, but I don't get any sound... I installed and built ALSA from their sourcem following the instructions at http://www.alsa-project.org/alsa-doc/doc-php/template.php?company=Analog+Dev ices&card=AD1980&chip=AD1980&module=via82xx (http://tinyurl.com/ywu3e). This builds 4 modules: snd-via82xx snd-pcm-oss snd-mixer-oss snd-seq-oss Running the install line (modprobe on each of those), I get a few errors on the first and last module: [root@dauphin sysconfig]# modprobe snd-via82xx;modprobe snd-pcm-oss;modprobe snd-mixer-oss;modprobe snd-seq-oss /lib/modules/2.4.22-1.2115.nptl/kernel/sound/pci/snd-via82xx.o: init_module: No such device Hint: insmod errors can be caused by incorrect module parameters, including invalid IO or IRQ parameters.

Windows (it's a dual-boot) says the sound module is using IRQ-22, which is of no help. Is there a utility that will help me truly detect the IRQ of the device? Once I do, does anyone know where I can specify the correct IRQ when loading the modules? Thanks for your help, and patience, -Don
