Backstory:
The patch "ALSA: hda - Add infrastructure for dynamic stream allocation"
http://git.alsa-project.org/?p=alsa-kmirror.git;a=commit;h=ae32c9fe811fed22715342494c08a11fabc87762
broke the detection of my card. With this patch applied the dmesg output is:
[ 3761.464838] ACPI: PCI Interrupt 0000:00:1b.0[A] -> GSI 16 (level,
low) -> IRQ 16
[ 3761.464863] PCI: Setting latency timer of device 0000:00:1b.0 to 64
[ 3761.499927] ACPI: PCI interrupt for device 0000:00:1b.0 disabled
[ 3761.499945] HDA Intel: probe of 0000:00:1b.0 failed with error -22
When I loaded the module with model=... then it would work only for some
models, but not for others. I found out that the ones which worked were the
ones with a digout. I added the digout to the F1734 model and now it is
working again.
I can't test if the digout is really working because I lack the hardware, but
when I turn on the IEC958 control in the mixer then red light is emitted from
my headphone port.
I will attach a patch that adds digout to this model because this seems the
right thing to do, but I don't know whether there is something wrong with the
aforementioned patch that caused my problem in the first place.
