I’m replying to myself to share the blog post I wrote detailing the steps I took to get it to work. I hope it’s useful for someone else out there: http://bit.ly/ypCcZ0 . Again, many thanks to Adrian Knoth and Florian Faber for all the help. best, Miguel Negrão A 08/12/2011, às 16:36, Miguel Negrao escreveu: > Hi all, > > I’m trying to configure a linux pc with 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.
