Unfortunately I don't know how to appropiately mail a follow-up to your
posting. So this post might not show up as a direct reply. Apologies for
that.
But to answer your questions:
My issue is not solved. In the meantime I switched to openSUSE 12.1
(kernel 3.1.9-1.4 desktop, 64bit). ALSA version reported by alsamixer is
1.0.24.
I also tried to write a quirk, put the following lines into
quirk-table.h and recompiled.
/*
* Fractal Audio Systems devices
*/
{
USB_DEVICE(0x2466, 0x8003),
.driver_info = (unsigned long) & (const struct
snd_usb_audio_quirk) {
.vendor_name = "Fractal Audio Systems",
.product_name = "AXE-FX II",
.ifnum = QUIRK_ANY_INTERFACE,
.type = QUIRK_COMPOSITE,
.data = & (const struct snd_usb_audio_quirk[]) {
{
.ifnum = 0,
.type = QUIRK_AUDIO_STANDARD_MIXER
},
{
.ifnum = 1,
.type = QUIRK_AUDIO_FIXED_ENDPOINT,
.data = & (const struct audioformat) {
.formats = SNDRV_PCM_FMTBIT_S24_3LE,
.channels = 2,
.iface = 1,
.altsetting = 1,
.altset_idx = 1,
.attributes = 0,
.endpoint = 0x02,
.ep_attr = 0x05,
.maxpacksize = 0x002a,
.rates = SNDRV_PCM_RATE_CONTINUOUS,
.rate_min = 48000,
.rate_max = 48000
}
},
{
.ifnum = 2,
.type = QUIRK_AUDIO_FIXED_ENDPOINT,
.data = & (const struct audioformat) {
.formats = SNDRV_PCM_FMTBIT_S24_3LE,
.channels = 4,
.iface = 2,
.altsetting = 1,
.altset_idx = 1,
.attributes = 0,
.endpoint = 0x86,
.ep_attr = 0x05,
.maxpacksize = 0x0054,
.rates = SNDRV_PCM_RATE_CONTINUOUS,
.rate_min = 48000,
.rate_max = 48000
}
},
{
.ifnum = 3,
.type = QUIRK_MIDI_STANDARD_INTERFACE
},
{
.ifnum = -1
}
}
}
},
As soon as the device is connected in /var/log/messages now appears:

And when I try to record with arecord I get the following:
arecord -c4 -f S24_3LE -r 48000 -d 10 -D plughw:3,0 test.wav
Aufnahme: WAVE 'test.wav' : Signed 24 bit Little Endian in 3bytes,

PERIOD_BYTES: 72000
PERIODS: 4
BUFFER_TIME: 500000
BUFFER_SIZE: 24000
BUFFER_BYTES: 288000

I would be very glad, if you could have a look at my quirk. Any help is
highly appreciated.
Joachim
P.S. The only sample valid rate for the Axe-FX II is 48000 Hz at 24bit.
