When module is loaded by hand it shows no error, but on `aplay samle.wav` I got "ALSA /work/install/alsa-driver-1.0.5a/alsa-kernel/core/pcm_lib.c:2172: playback write error (DMA or IRQ trouble?" on boot with 2.4.x kernel, everything magically works (alsaconf, aplay etc..) the bug is reported 4 months ago on http://bugzilla.kernel.org/show_bug.cgi?id=3117 that's why some versions are old (but I had tried alsa-1.0.8 before reposting this bug here) ====================================================================== Relationships ID Summary ---------------------------------------------------------------------- related to 0001296 isapnp is incompatible with pnpbios and... ====================================================================== ---------------------------------------------------------------------- perex - 08-08-05 13:45 ---------------------------------------------------------------------- iive: Thanks for testing. Please, could you send me related ALSA lines from /etc/modules.conf or /etc/modprobe.d/sound (depending on distro) and contents of /sys directory when snd-opl3sa2 module is loaded? Also, please,try to override dma1, dma2 and irq parameters in the modprobe configuration file. (For example: options snd-opl3sa2 dma1=3 dma2=1 irq=9). Check for free irqs in /proc/interrupts and for dmas in /proc/dma. ---------------------------------------------------------------------- ahaning - 08-09-05 03:00 ---------------------------------------------------------------------- Well, with the help of some people on LKML, I've successfully built module-init-tools 3.2-pre7. I've installed alsa-utils-1.0.9 with the above patch and installed the above-attached alsaconf. When I run alsaconf 1.0.9a, it does not detect my card as a PnP card. It will brute-force detect the card, however. The dma1, dma2, and irq are wrong, though. When I fix them in the modprobe.conf file, I can do 'alsasound restart' and the card appears to be detected. When I go to play something, I won't get sound until I touch the PCM mixer. If it would help, I can repost my /sys directory. Thanks.
