[LAU] delta 1010 (yes) / delta 2496 (no)

[David Santamauro]

Hi, although sidetracked by life for a while, I finally got around to 
rebuilding my linux audio box.

It's a stock fedora 18:
Linux faure 3.8.5-201.fc18.x86_64 #1 SMP

GIGABYTE GA-Z68X
Intel(R) Core(TM) i7-2600 CPU @ 3.40GHz
16GB RAM


According to lspci -v, recognized are

... internal HDAC

00:1b.0 Audio device: Intel Corporation 6 Series/C200 Series Chipset 
Family High Definition Audio Controller (rev 05)
         Subsystem: Giga-byte Technology Device a102
         Flags: bus master, fast devsel, latency 0, IRQ 48
         Memory at fbff4000 (64-bit, non-prefetchable) [size=16K]
         Capabilities: <access denied>
         Kernel driver in use: snd_hda_intel

... an HDMI HDAC (nvidia)

02:00.1 Audio device: NVIDIA Corporation High Definition Audio 
Controller (rev a1)
         Subsystem: Device 196e:0877
         Flags: bus master, fast devsel, latency 0, IRQ 18
         Memory at faffc000 (32-bit, non-prefetchable) [size=16K]
         Capabilities: <access denied>
         Kernel driver in use: snd_hda_intel


.. the delta 1010 and 2496

05:00.0 Multimedia audio controller: VIA Technologies Inc. ICE1712 
[Envy24] PCI Multi-Channel I/O Controller (rev 02)
         Subsystem: VIA Technologies Inc. M-Audio Delta Audiophile 2496
         Flags: medium devsel, IRQ 19

         I/O ports at df40 [size=64]
         Capabilities: <access denied>

[Envy24] PCI Multi-Channel I/O Controller (rev 02)
         Subsystem: VIA Technologies Inc. M-Audio Delta 1010
         Flags: bus master, medium devsel, latency 32, IRQ 16
         I/O ports at df80 [size=32]
         I/O ports at dfd0 [size=16]

         Capabilities: <access denied>
         Kernel driver in use: snd_ice1712

All is well with every device except the delta 2496

$ cat /proc/asound/cards
  0 [M1010          ]: ICE1712 - M Audio Delta 1010
                       M Audio Delta 1010 at 0xdf80, irq 16
  1 [PCH            ]: HDA-Intel - HDA Intel PCH
                       HDA Intel PCH at 0xfbff4000 irq 48
  2 [K61            ]: USB-Audio - K61
                       KORG INC. K61 at usb-0000:00:1a.0-1.5, full speed
  3 [NVidia         ]: HDA-Intel - HDA NVidia
                       HDA NVidia at 0xfaffc000 irq 18

I've shuffled the cards around the slots to no avail (only have 2 PCI 
slots).

Could it be because they share the same bus (05) that somehow they don't 
work together? Also, regardless of which slot the physical cards are 
inserted into, only the delta 1010 is ever exposed by ALSA. To be sure, 
I also confirmed that the 2496 does indeed work by inserting it into a 
different test box.

Any insight would be appreciated.
