xubuntu 16.04, sis7012 (snd_intex8x0), no sound

Asked by Roman

Hello. I have an old laptop with SIS7012 sound chip on board. Currently I cannot make it working due to strange problems.
user@Rover:/etc$ lspci

01:00.0 VGA compatible controller: Silicon Integrated Systems [SiS] 65x/M650/740 PCI/AGP VGA Display Adapter

I have tried
modprobe snd_inter8x0
but nothing is changed.
I have still have not sound enabled on my laptop.
Alsamixer als cannot be started. It produces the error "Cannot open mixer: no such file or catalog".

After checking dmesg I have found strange error:
snd_intel8x0 0000:00:02.7: can't find IRQ for PCI INT C
genirq: Flags mismatch irq 0. 00000080 (snd_intel8x0) vs. 00015a00 (timer)
snd_intel8x0 0000:00:02.7: unable to grab IRQ 0

I have tried to add a kernel parameter "pci=biosirq" as it was proposed in dmesgm but it didn't help. The message above is still in dmesg.

Seems the driver is found correctly, because SIS7012 must be supported by alsa driver snv_intel8x0 regarding alsa's specs, but it cannot to be loaded due to some kernel-bios inconsitency.

(Also before xubuntu I have used windows XP and sound chip worked correctly).

Does anyone know how to solve this error in xubuntu (I don't want to return to windows xp)?

Interesting problem.

Your Terminal output shows this error:

[ 21.648744] snd_intel8x0 0000:00:02.7: can't find IRQ for PCI INT C
[ 21.929632] genirq: Flags mismatch irq 0. 00000080 (snd_intel8x0) vs. 00015a00 (timer)
[ 21.929656] snd_intel8x0 0000:00:02.7: unable to grab IRQ 0
[ 21.929728] snd_intel8x0: probe of 0000:00:02.7 failed with error -16

This looks like an ACPI or IRQ misconfiguration issue at the level of the BIOS or a misconfiguration of the kernel boot parameters.

I have 3 suggestions:

1) upgrading the kernel from version 4.8.0-36-generic to kernel version 4.10 or newer to try to fix the ACPI or IRQ issue with your Roverbook Navigator E416 (KT6) (M220S) laptop.

2) using Linux kernel boot option "nomodeset" instead of boot option "acpi=off"

See https://help.ubuntu.com/community/BootOptions

3) Manually set a different IRQ for your sound card in the BIOS of your laptop (if possible). If you have a BIOS conflict, be sure to check your BIOS settings to see if some of the items can be turned off temporarily (serial ports, etc.).

See

https://help.ubuntu.com/community/DebuggingIRQProblems

for other IRQ related suggestions.

Can you help with this problem?
