hda-intel: no codecs initialized with Teradici sound card and ALSA 1.0.17

hda-intel: no codecs initialized with Teradici sound card and ALSA 1.0.17

[James Pearson]

I'm using CentOS 5.3 (which uses ALSA 1.0.17) and a Teradici KVM over IP 
extender - which has an hda_intel type sound chipset

However, when the snd_hda_intel module is loaded, dmesg reports:

PCI: Enabling device 0000:04:00.1 (0000 -> 0002)
ACPI: PCI Interrupt 0000:04:00.1[A] -> GSI 16 (level, low) -> IRQ 177
PCI: Setting latency timer of device 0000:04:00.1 to 64
hda-intel: no codecs initialized
ACPI: PCI interrupt for device 0000:04:00.1 disabled

... and /proc/asound/cards reports:

--- no soundcards ---

I've tried loading the snd-hda-intel module with various 'model=' 
options (including basic and auto), but it makes no difference

However, we also have CentOS 4.7 on machines with same Teradici card 
using ALSA 1.0.15 (that replaces the ALSA version that ships with CentOS 
4) patched to support the Teradici card - using a patch based on the one 
that went into ALSA 1.0.17 to support the Teradici card. In this case 
the audio works - dmesg reports:

ACPI: PCI Interrupt 0000:82:00.1[A] -> GSI 47 (level, high) -> IRQ 233
PCI: Setting latency timer of device 0000:82:00.1 to 64
hda_codec: Unknown model for ALC883, trying auto-probe from BIOS...

And in this case, /proc/asound/cards reports:

  0 [Teradici       ]: HDA-Intel - HDA Teradici
                       HDA Teradici at 0xd0100000 irq 233

and playback works fine.

Any idea why ALSA 1.0.17 doesn't work with the Teradici card?

I don't really want to replace the the ALSA kernel code with a more up 
to date version if at all possible ... is there a way of 'forcing' the 
1.0.17 code 'to work' ?

This means that the driver is loaded but the codec wasn't found
on the hardware.  It's rather a hardware issue, as it seems.

But the same card works with ALSA 1.0.15 - patched to support the 
Teradici controller - using a patch based on:

<http://marc.info/?l=git-commits-head&m=121607380317261&w=2>

So how can it be a hardware issue?

I'm going to see if a more recent version of ALSA works ...

Well, if exactly the same machine works, then it's hardly.

Yes please.  1.0.17 is way too old to debug.

Strangely, using a generic 1.0.17 alsa-driver - and the card works fine ...

So I guess it something strange in what RedHat do to their version of 
the ALSA drivers ...
