Bug Description

The SiS 7012 Sound Controller is detected by lspci...

fabio@ubuntu:~$ lspci|grep Sound
0000:00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] Sound Controller (rev a0)

-----------------------------------------------------------------------

... and the modules are loaded when I start Ubuntu:

fabio@ubuntu:~$ lsmod|grep snd
snd_intel8x0 35740 0
snd_ac97_codec 99808 1 snd_intel8x0
snd_ac97_bus 2400 1 snd_ac97_codec
snd_pcm_oss 56448 0
snd_mixer_oss 20544 1 snd_pcm_oss
snd_pcm 96676 3 snd_intel8x0,snd_ac97_codec,snd_pcm_oss
snd_timer 26884 1 snd_pcm
snd 60004 6 snd_intel8x0,snd_ac97_codec,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer
soundcore 10784 1 snd
snd_page_alloc 11304 2 snd_intel8x0,snd_pcm

-----------------------------------------------------------------------

But the sound card is "dead":

fabio@ubuntu:~$ tail /proc/asound/cards
--- no soundcards ---

-----------------------------------------------------------------------

This is the dmesg output:

fabio@ubuntu:~$ dmesg|grep 0000:00:02.7
[4294687.486000] PCI: Enabling device 0000:00:02.7 (0000 -> 0001)
[4294687.486000] ACPI: PCI Interrupt 0000:00:02.7[C] -> GSI 18 (level, low) -> IRQ 193

[4294688.740000] Intel ICH: probe of 0000:00:02.7 failed with error -13

-----------------------------------------------------------------------

I don't know what to do. This is a anormal situation to me :P
If somebody needs more information, I will post it.

1) Which kernel? (``uname -r'')
2) Try booting with "acpi=off" appended to the kernel command line. If that fails to produce audible sound, too, try adding "noapic".

2)I tried acpi=off and noapic, but didn't work too...

fabio@ubuntu:~$ dmesg|grep 02.7
[ 12.777107] PCI->APIC IRQ transform: 0000:00:02.7[C] -> IRQ 65

I'm getting "--- no soundcards ---" always.

There is a little strange output when I run a gnome program in terminal:

fabio@ubuntu:~$ gconf-editor
ALSA lib confmisc.c:672:(snd_func_card_driver) cannot find card '0'

(No sound driver being loaded will give you such errors.)

maybe, but the respective module for this chip is loaded (snd_intel)

what can I do now?

Can you check if this is related to Bug #19648 and if the workaround described there helps ?
