Hi all,
I’m trying to configure a pc with puredyne and 2 RME HDSPM soundcards[1]. I
manage to get sound perfectly, and I also managed to merge the two sound cards
into one using .asoundrc. My problem is that the cards are identical and at
every boot they get a random order. I was trying to follow [2] to try to give
them a name based on the hardware location of the pci cards.
I created a file which I placed in /etc/udev/rules.d/85-wfs-script.rules with
the following:
SUBSYSTEM!="sound", GOTO="wfs_pci_cards"
ACTION!="add", GOTO="wfs_pci_cards"
DEVPATH=="/devices/pci0000:00/0000:00:14.4/0000:02:0e.0/sound/card?",
ATTR{id}="HDSPM_1"
DEVPATH=="/devices/pci0000:00/0000:00:14.4/0000:02:09.0/sound/card?",
ATTR{id}="HDSPM_2"
LABEL="wfs_pci_cards"
Then when I reboot or reload the driver I get one of them with the correct name
and the other one with “default”
/proc/asound/cards
0 [default ]: HDSPM - HDSPM MADI
RME HDSPM MADI at 0xfdce0000, irq 16
1 [HDSPM_1 ]: HDSPM - HDSPM MADI
RME HDSPM MADI at 0xfdcd0000, irq 17
Which one gets the “default” name is random and changes every time I boot. I
tried changing the number 85 to all sorts of numbers, to change the order in
which the rule is run, but it doesn’t really make a difference. Running udevd
--debug and reloading the driver reports :
1323357358.505334 [3088] udev_rules_apply_to_event: ATTR

ATTR{/sys/devices/pci0000:00/0000:00:14.4/0000:02:09.0/sound/card0/id} for

Btw, the file is there, and doing "more
/sys/devices/pci0000:00/0000:00:14.4/0000:02:09.0/sound/card0/id” yields “default”
or “default_1”.
How can I stop the “default” name overriding the names that I set in the .rules
file ? Any help appreciated !!!!
best regards,
