 |

I'm stumped. I've been trying to setup a mythtv box with gentoo, and everything has been going great except for the sound. I'm having some seriously bad sound karma. I've wasted hours on this.
I have a WinTV Go in the box which needs to get its sound by a passover cable to the line in on the soundcard. Trouble was, the soundcard in the box I was using was a SB Audigy Live 7.1 24-bit (SB0410). I got sound working with the ca0106 driver but recording was a no go. Googling seemed to indicate that recording wasn't supported by the alsa drivers yet. No problem, I'll just swap out the old SB Live 5.1 from another box of mine which I know has worked for years with the emu10k1 driver.
Well, apparently the hardware felt otherwise. Here's the dmesg output:
| Code: |
PCI: 0000:00:08.0 has unsupported PM cap regs version (7)

lsmod shows that the snd_emu10k1 driver is loaded. Alsa compiled from kernel. cat /proc/asound/cards shows no sound cards. WHAT THE HECK MAN! Just to make sure it wasn't a Gentoo problem I booted an Ubuntu Live CD. No sound! Same dmesg output. Well it ain't Gentoo's fault...ripped the card out of the machine and put it back into my old Ubuntu dapper machine...works...perfectly.
I KNOW that I HAD Debian with a 2.4 kernel and this card working on this exact machine before. What...happened? Hardware problem? Aliens? The Gods like to !@#$% with me? I'm teed off, I was supposed to be done with my pet project by now!
Any and all help is greatly appreciated, including confirmation that there's a way to get my other card, the SB Audigy Live 7.1 24-bit (SB0410) recording off the line in with the ca0106 driver. This is the only thing that needs to work to have my myth box finished. |

You seem to be having an IRQ routing problem.
This could be caused by a crappy BIOS and/or motherboard chipset.
Usually, the best workaround is to move the soundcard to a different PCI slot.
If that doesn't help, then you could try booting with kernel parameters like "acpi=off" or "pci=noacpi". |
