Dear Mr. Iwai,

I put only those lines in my asound.conf file and I still got this
output:

/etc # speaker-test

speaker-test 1.0.13

Playback device is default
Stream parameters are 48000Hz, S16_BE, 1 channels
Using 16 octaves of pink noise
ALSA lib pcm_plug.c:773:(snd_pcm_plug_hw_refine_schange) Unable to
find an usable access for 'default'
Sample format not available for playback: Invalid argument
Setting of hwparams failed: Invalid argument

I put back the original ca0106 stuff at the beginning of my
asound.conf file, as in

pcm.ca0106 {
    type hw
    card 0
}

ctl.ca0106 {
    type hw
    card 0
}

pcm.!default {
    type plug
    slave.pcm {
        type hw
        card 0
    }
}

but I still got the same error when I ran speaker-test.  Should I
punt and try to implement your suggested version of dma_mmap_coherent?
