Status update:
* Can use alsamixer to control how much of the mic signal that should be heard in speakers.
* Can not play audio.

What is done:
* I patched openwrt/build_dir/linux-etrax/linux-2.6.25.16/arch/cris/Kconfig with 'source "sound/Kconfig"' as Claudio suggested.
* Compiled ALSA and usb sound enabled.
* Copied modules and config files (/usr/share/alsa/) to my foxboard. I think the config files should be part of alsa-utils, but it wasn't installed automatically.
* Added a file /etc/modules.d/50-alsa-sound with this contents:
soundcore
snd
snd-seq-device
snd-page-alloc
snd-hwdep
snd-timer
snd-rawmidi
snd-mixer-oss
snd-pcm
snd-pcm-oss
snd-usb-lib
snd-usb-audio

* Installed packages alsa-lib, alsa-utils, and madplay for playing mp3.

* Tried sending data to sound card:

madplay -o cdda:- sound.mp3 | aplay -f cdr
also tried:
echo "hello" > /dev/dsp
to see if I could get a noise out of the audio card through OSS emulation.

No sound heard. Took lots of execution time, and I could read using dmesg:

 drivers/usb/host/hc-crisv10.c: assert failed at: tc_dma_process_queue 3522
drivers/usb/host/hc-crisv10.c: assert failed at: tc_dma_process_queue 3523
crisv10_late dbg: Later finish of URB:0xc1eb0ac0[5284]

drivers/usb/host/hc-crisv10.c: assert failed at: tc_dma_process_queue 3523
crisv10_late dbg: Later finish of URB:0xc1eb01c0[5285]

This is from hc-crisv10.c:
3520  urb_priv = urb->hcpriv;
3521  ASSERT(urb_priv != NULL);
3522  ASSERT(urb_priv->urb_state == NOT_STARTED);
3523  ASSERT(!usb_pipeisoc(urb->pipe));

Salvatore, the patch you mailed me just seem to be a port of USB host from kernel version 2.6.19 to 2.6.26.
The crisos version I'm running is using kernel 2.6.25 and the following USB host:
ETRAX 100LX USB Host Controller (2.6.25-rc9 port)

Any suggestions?

Perhaps simply changing volume during sound recording/reproduction...
