Audio woes on F11

[Chris]

Hi, I've got an M-Audio Audiophile 2496 card (ICE1712 chip) running on
an AMD 64 bit CPU (can't remember exact model right now). I originally
installed F11 x86_64 and had a few sound problems, but it worked if I
disabled pulse audio.

I've just had to install the 32-bit version of Fedora 11 due to some
work constraints (long story!). Now I can't get audio to work at all.

Firstly, my user was not part of the pulse-rt group so I added myself
manually. This didn't happen when I installed the x86_64 version on
the same PC which seems strange.

Secondly, I can't get audio to work at all. I've checked the Advance
Volume Control and turned everything up. /var/log/messages shows the
following:

Jun 30 21:33:20 localhost pulseaudio[2106]: module-alsa-card.c: Failed
to find a working profile.
Jun 30 21:33:20 localhost pulseaudio[2106]: module.c: Failed to load
module "module-alsa-card" (argument: "device_id=0
name=usb_device_944_103_noserial_if0_sound_card_0
card_name=alsa_card.usb_device_944_103_noserial_if0_sound_card_0
tsched=1"): initialization failed.

Not quite sure why it mentions USB device since it's a PCI card.

lsmod shows the right module amongst the others although it's not used:

Whenever I try to run alsamixer or pavucontrol when pulse is not
running, I get this:

shm_open() failed: No such file or directory
ALSA lib pulse.c:272:(pulse_connect) PulseAudio: Unable to connect: Connection
efused


alsamixer: function snd_ctl_open failed for default: Connection refused

Maybe that's expected since pulse is not running.

I should also mention that I dual-boot Windows and it works fine there.

So, any ideas or recommendations for how to investigate?

Thanks in advance, Chris.
