I just noticed that the driver in the 1.0.24 release tarball doesn't
contain the latest fixes we already have in the git repo.

I reckon the PCI version has an "unknown" revision ID. We added a
default case a couple of month ago to prevent the kernel from crashing:

	default:
		snd_printk(KERN_ERR "HDSPM: unknown firmware revision %x\n",
				hdspm->firmware_rev);
		return -ENODEV;
	}

I suggest you use this file instead of the 1.0.24 tarball:


http://git.alsa-project.org/?p=alsa-kernel.git;a=blob_plain;f=sound/pci/rme9652/hdspm.c;hb=HEAD

If you send me the revision ID of your PCI MADI card, I'll come up with
a patch.
