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 dfa0 [size=32]
I/O ports at dff0 [size=16]
I/O ports at dfe0 [size=16]
I/O ports at df40 [size=64]
Capabilities: <access denied>
05:01.0 Multimedia audio controller: VIA Technologies Inc. ICE1712
[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]
I/O ports at dfc0 [size=16]
I/O ports at df00 [size=64]
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.
David
