need help getting echo indigo io to work

[Phil Frost]

It looks like no one can help on the user list, so I'm reposting this
here. In addition to the information I have below, I've traced the
problem a bit more.

By what I can tell by peppering the code with log messages, the failure
occurs in the kernel in drivers/base/firmware_class.c around line 431:

if (!fw_priv->fw->size || test_bit(FW_STATUS_ABORT, &fw_priv->status)) {
        retval = -ENOENT;
        ...

I've never done any kernel development, so I have no clue how to debug
this. Any help would be appreciated.

Subject: [Alsa-user] need help getting echo indigo io to work

I recently purchaced an echo indigo io, a pcmcia sound device. I'm
trying to get it to work.

I started with the stock ubuntu kernel 2.6.10-5, but this has an old
alsa version and aparently the indigoio driver is not included with the
kernel sources anyway.

I downloaded, built and installed alsa-driver 1.0.9b, then alsa-firmware
1.0.9 without problems. /proc/asound/version shows:

Advanced Linux Sound Architecture Driver Version 1.0.9b.
Compiled on Jul 18 2005 for kernel 2.6.10-5-386.

Now when I insert the card, something seems to notice and the
snd_indigoio module is loaded successfully, but I do not see my card in
/proc/asound/cards.

Looking at dmesg, I see this:

ALSA /.../echoaudio.c:1870: Echoaudio driver starting...
PCI: Enabling device 0000:03:00.0 (0000 -> 0002)

ALSA /.../echoaudio.c:1753: Chip freed.
Echoaudio Indigo IO: probe of 0000:03:00.0 failed with error -2

I don't know much about how firmware loading should work, but I did
manage to find that /etc/hotplug/firmware.agent seems to be responsible
for finding the firmware. By putting some echos in there I traced what
it was doing, and it generates this output:

looking for ea/indigo_io_dsp.fw-2.6.10-5-386
looking in /lib/hotplug/firmware
looking in /usr/local/lib/hotplug/firmware
looking in /usr/lib/hotplug/firmware
loading /usr/lib/hotplug/firmware/ea/indigo_io_dsp.fw
loaded /usr/lib/hotplug/firmware/ea/indigo_io_dsp.fw > /sys//class/firmware/0000:03:00.0/data

So aparently, it does find the firmware and sends it off somewhere to be
loaded. I don't know what should happen next, or where or why it could
be failing. Ideas, anyone?

Many thanks,
Phil

Sounds like a driver bug to me.  A bunch of driver model stuff changed
recently in the kernel, I suspect the echo driver was developed against
a newer version.

I suspect it would work with 2.6.12.

It's 17 kb away from empty. Also, firmware.agent seems to complete
successfuly from what I can tell. Lee Revell suggested on alsa-devel
that I should try with 2.6.12 since there have been changes in the
driver model since 2.6.10 (what i'm using). Indeed that seems to have
been the cause of the problem. With 2.6.12 I was able to play audio
nicely.

However, with 2.6.12 both support for my video hardware (radeon mobility
m6 ly on a sharp mm20 laptop) and my wireless network (prism) is broken.
I guess I have the choice between being blind or deaf. :(

Ugh, not again...

Try the latest stable kernel, 2.6.12.3 I think.

Also how does it break?
