hiho,
i encountered some problems after upgrading to kernel 2.6.19-rc4 vanilla from
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 changes
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) -> IRQ 5

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
marcel
