[Alsa-user] snd_hda_intel on Asus M2N32 WS Pro Asus MB

[Mws <mw...@tw...>]

hiho,

i encountered some problems after upgrading to kernel 2.6.19-rc4 vanilla fr=
om=20
kernel org.
sound from the soundcard is very crappy, scratches when basses are played,
ect.

i didn't have this behaviour before and i noticed, that you made some chang=
es
in sound/pic/hda/....

at least sound has been working nearly fine with kernel 2.6.18-rc5.
i just tested this again some mins ago to be safe on my side depending on
technical issues.

the 2.6.18-rc5 dmesg output when detecting the device is as follows

ACPI: PCI Interrupt Link [LAZA] enabled at IRQ 5
ACPI: PCI Interrupt 0000:00:0e.1[B] -> Link [LAZA] -> GSI 5 (level, low) ->=

seems to be nearly the same except for the MSI adress&data and of course
irq pin B is routed to 21 instead of 5

any hints to get this working properly again?
also testing patches are welcome.

additional info, if i rmmod snd_hda_intel and afterwards try to modprobe it=
 again
my machine totally freezes, nothing is working anymore


i would appreciate your help.

best regards
