Lo all, Running 5.0-RELEASE with 'device pcm' in my kernel, and now I see this is happening: Dump from /var/log/messages: Feb 23 14:59:20 Hobbes kernel: sbc0: <ESS ES1868> at port 0x300-0x301,0x388-0x38b,0x220-0x22f irq 10 drq 0,1 on isa0 Feb 23 14:59:20 Hobbes kernel: pcm0: <ESS 18xx DSP> on sbc0 Feb 23 14:59:20 Hobbes kernel: midi0: <SB Midi Interface> on sbc0 Feb 23 14:59:20 Hobbes kernel: midi1: <SB OPL FM Synthesizer> on sbc0 Feb 23 14:59:20 Hobbes kernel: joy0: <ESS0001 PnP Joystick> at port 0x201 on isa0 Feb 23 14:59:20 Hobbes kernel: unknown: <ESS ES1868 Plug and Play AudioDrive> can't assign resources (irq) So, according to the BIOS startup messages and DMESG, should be assigned no DMA, and an IRQ of 10. And no, I do *not* have device sbc in my kernel. Anyway, I added this line to /boot/device.hints: hint.pcm.0.irq="10" Has no effect, still getting the same message. Any ideas? Oh, if I ignore the fact that the error's there, and try mpg321 or anything to play sound (even if I cat a .au into /dev/dsp0), it gives me this: Feb 23 14:59:44 Hobbes kernel: pcm0:play:0: play interrupt timeout, channel dead Interestingly enough, there appear to be problems with a lot of interrupt assignments. When I had ACPI disabled in the BIOS, then it moaned about assigning interrupts to the AGP card. ACPI and APM are enabled in the BIOS, I've tried disabling APM (don't ask why I thought it would make a difference:) Also, the BIOS (Award) has some simple settings for enabling/disabling a PNP-OS, allowing the OS to set IRQs et. al. Dunno if that has any bearing tho...
