hi all,
(posted the same message on the alsa-user list, but without reply, now trying
here)
i have a machine with two pci devices of the same type. how can i ensure
persistent device indices?
the wiki [1] mentions a way for a way using vid/pid, but for pci devices it
suggests to write a udev rule. [2] has an example, but it only describes how to
set up the device names in /dev/snd. but how do i bind a specific device to an
alsa device index (hw:X)?
thanks, tim

Doesn't specifying the pid (product id) work ?
I'm not sure myself, which is the pid for PCI devices.
Any of the numbers listed by lspci ? :
sudo update-pciids
lspci -nn

surely not if they are the same device? there needs to a mapping from
a PCI bus slot to a device name.

Sounds convincing.
Tim, you could try to use the additional "id" option, instead of pid.
(I didn't try that myself so far.)
Assuming, the id is different, for each device, of course.
Is it ?
for example
modinfo snd_ice1712
or
modinfo -p snd_ice1712
tells me, that the parameter id is supported:
parm: id:ID string for ICE1712 soundcard. (array of charp)
The options line would then look as
options snd-ice1712 index=1,2 id=0x0033,0x0044

^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

course.

Apparently not.
I've run into this with my studio machine which has 2 Delta 1010s
in it. It at least consistently indexes the cards correctly across
reboots so I know which one is 0 and which is 1, but but if I make
any changes to the PCI bus, this can change (and has).

In theory, there should be some configuration tool to create the
configuration file.
Anyway, for identical devices, you have to haul out the big guns:

this is the second important ALSA documentation link to fail that we have
linked to from jackaudio.org. is it really this impossible to expect a wiki
to stay up or at least redirect?
clemens - do you have any other copy of that document?
3:06 p.m.
No i don't have a copy and that document is important for me.
