I have unmuted (of course), I have OSS API emulation enabled, I see interrupts being fired, apparently the ALSA subsystem can see the card (some /proc/asound/* output below). I have also looked at the settings with the ALSA utilities, to double-check that ALSA is in fact recognizing... everything YMF744, AC97, etc checks out. My applications just look like they are playing sound, while only a crack comes out of my speakers every once in a while. Can anyone give me some pointers on how best to debug my problem? I have enabled sound debug and verbose printk in the kernel, but I'm not clear on how to use the debug facility.
